Drop use of the deprecated drmP.h header.
While doing so used the opportunity
to clean up a little so includes are now
sorted and removed unused include files.
In a few cases added some forwards to allow header
files to built in different include order.

Since Linux 4.17, calls to drm_crtc_vblank_on/off are mandatory, and we get
a warning when ctrc is disabled :
" driver forgot to call drm_crtc_vblank_off()"
But, the vsync IRQ was not totally disabled due the transient hardware
state and specific interrupt line, thus adding proper IRQ masking from
the HHI system control registers.
The last change fixes a race condition introduced by calling the added
drm_crtc_vblank_on/off when an HPD event occurs from the HDMI connector,
triggering a WARN_ON() in the _atomic_begin() callback when the CRTC
is disabled, thus also triggering a WARN_ON() in drm_vblank_put() :

The issue is that vblank need to be enabled in any occurrence of :
- atomic_enable()
- atomic_begin() and state->enable == true, which was not the case
Moving the CRTC enable code to a common function and calling in one of
these occurrence solves this race condition and makes sure vblank is
enabled in each call to _atomic_begin() from the HPD event leading to
drm_atomic_helper_commit_planes().
To Summarize :
- Make sure that the CRTC code will call the drm_crtc_vblank_on()/off()
- *Really* mask the Vsync IRQ
- Initialize and enable vblank at the first
atomic_begin()/_atomic_enable()

Remove the modes timings tables for DMT modes and calculate the HW
paremeters from the modes timings.
Switch the DMT modes pixel clock calculation out of the static frequency
list to a generic calculation from a range of possible PLL dividers.
This patch is an intermediate step towards usage of the Common Clock
Framwework for PLL setup, by reworking the code to have common
sel_pll() function called by the CEA (HDMI) freq setup and the generic
DMT frequencies setup, we should be able to simply call clk_set_rate()
on the PLL clock handle in a near future.
The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will
never be able to determine by itself, so there is still some work to do for
a full handoff to CCF handling the clocks.
This setup permits setting non-CEA modes like :
- 1600x900-60Hz
- 1280x1024-75Hz
- 1280x1024-60Hz
- 1440x900-60Hz
- 1366x768-60Hz
- 1280x800-60Hz
- 1152x864-75Hz
- 1024x768-75Hz
- 1024x768-70Hz
- 1024x768-60Hz
- 832x624-75Hz
- 800x600-75Hz

The Amlogic Meson Display controller is composed of several components :
DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|

A | osd1 | | | Blenders | | Encl ----------|----|---------------|
M |-------|______|----|____________| |________________| | |
___|__________________________________________________________|_______________|
VIU: Video Input Unit
---------------------
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
This part is also in charge of the CSC (Colorspace Conversion).
It can handle 2 OSD Planes and 2 Video Planes.
VPP: Video Post Processing
--------------------------
The Video Post Processing is in charge of the scaling and blending of the
various planes into a single pixel stream.
There is a special "pre-blending" used by the video planes with a dedicated
scaler and a "post-blending" to merge with the OSD Planes.
The OSD planes also have a dedicated scaler for one of the OSD.
VENC: Video Encoders
--------------------
The VENC is composed of the multiple pixel encoders :
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- ENCP : Progressive Video Encoder for HDMI
- ENCL : LCD LVDS Encoder
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
tree and provides the scanout clock to the VPP and VIU.
The ENCI is connected to a single VDAC for Composite Output.
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
This driver is a DRM/KMS driver using the following DRM components :
- GEM-CMA
- PRIME-CMA
- Atomic Modesetting
- FBDev-CMA
For the following SoCs :
- GXBB Family (S905)
- GXL Family (S905X, S905D)
- GXM Family (S912)
The current driver only supports the CVBS PAL/NTSC output modes, but the
CRTC/Planes management should support bigger modes.
But Advanced Colorspace Conversion, Scaling and HDMI Modes will be added in
a second time.
The Device Tree bindings makes use of the endpoints video interface definitions
to connect to the optional CVBS and in the future the HDMI Connector nodes.
HDMI Support is planned for a next release.
