The Processor Thermal PCI device supports multiple features. Currently
we export only RAPL. But we need more features from this device exposed
for Tiger Lake and Alder Lake based platforms. So re-structure the
current MMIO interface, so that more features can be added cleanly.
No functional changes are expected with this change.
Changes done in this patch:
- Using PCI_DEVICE_DATA(), hence names of defines changed
- Move RAPL MMIO code to its own module
- Move the RAPL MMIO offsets to RAPL MMIO module
- Adjust Kconfig dependency of PROC_THERMAL_MMIO_RAPL
- Per processor driver data now contains the supported features
- Moved all the common data structures and defines to a common header
file
- This new header file contains all the processor_thermal_* interfaces
- Based on the features supported the module interface is called
- Each module atleast provides one add and one remove function

The PAT bit is in different locations for 4k and 2M/1G page table
entries.
Add a definition for _PAGE_LARGE_CACHE_MASK to represent the three
caching bits (PWT, PCD, PAT), similar to _PAGE_CACHE_MASK for 4k pages,
and use it in the definition of PMD_FLAGS_DEC_WP to get the correct PAT
index for write-protected pages.

Add support for M_CAN controller on Intel Elkhart Lake attached to the PCI bus.
It integrates the Bosch M_CAN controller with Message RAM and the wrapper IP
block with additional registers which all of them are within the same MMIO
range.
Currently only interrupt control register from wrapper IP is used and the MRAM
configuration is expected to come from the firmware via "bosch,mram-cfg" device
property and parsed by m_can.c core.
Initial implementation is done by Felipe Balbi while he was working at Intel
with later changes from Raymond Tan and me.

This is a preparatory patch for upcoming PCI based M_CAN devices. The current
PM implementation would cause PCI based drivers to enable PM twice, once when
the PCI device is added and a second time in m_can_class_register(). This will
cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that
should be avoided.
Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN
class registration to its only user, the m_can_platform driver.

When CAN_ISOTP_SF_BROADCAST is set in the CAN_ISOTP_OPTS flags the CAN_ISOTP
socket is switched into functional addressing mode, where only single frame
(SF) protocol data units can be send on the specified CAN interface and the
given tp.tx_id after bind().
In opposite to normal and extended addressing this socket does not register a
CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a
segmented bi-directional data transfer.
Sending SFs on this socket is therefore a TX-only 'broadcast' operation.

The R-Car V3U clock driver defines the R and OSC clocks using R-Car Gen3
clock types. However, The R-Car V3U clock driver does not use the R-Car
Gen3 clock driver core, hence registering the R and OSC clocks fails:
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock osc: -22
renesas-cpg-mssr e6150000.clock-controller: Failed to register core clock r: -22
Fix this by introducing clock definition macros specific to R-Car V3U.
Note that rcar_r8a779a0_cpg_clk_register() already handled the related
clock types. Drop the now unneeded include of rcar-gen3-cpg.h.

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.
For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.
To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.
