Previously, possible digital gains were just 1x, 2x and 4x. These
coarse gains were not sufficient in fine-tuning the image capture.
Now, digital gain range is [0, 16x] with each step 1/1024, default 1x.
This is achieved through OV13858 MWB R/G/B gain controls.

On format change, sometimes, sensor was streaming at a much higher
FPS than the default. This was resulting in various problems like
frame drops/corruption.
Upon format change, set default vblank as current vblank. This will
ensure that sensor will start streaming at default fps.

These can only be accessed with CAP_SYS_ADMIN so it's not a critical
security issue. The problem is that "page" is controlled by the user in
the ioctl(). The test to see if the bit is set in state->info->page_mask
is not sufficient because "page" can be very high and shift wrap around
to a bit which is set.

Remove unnecessary static on local variable rtype. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces

entities.
The HDMI entity is linked to the TXA CSI bus, whilst the AFE is linked

Commit e789029761 ("i2c: sh_mobile: don't send a stop condition by
default inside transfers") makes the i2c_sh_mobile I2C-adapter emit a
stop/start sequence between messages in a single transfer only when
explicitly requested with I2C_M_STOP.
This breaks the ov772x driver in the SH4 Migo-R board as the Omnivision
sensor uses the I2C-like SCCB protocol that doesn't support repeated
starts:
i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out
ov772x 0-0021: Product ID error 92:92
Fix it by marking the client as SCCB, forcing the emission of a
stop/start sequence between all messages.
As I2C_M_STOP requires the I2C adapter to support protocol mangling,
ensure that the I2C_FUNC_PROTOCOL_MANGLING functionality is available.
Tested on SH4 Migo-R board, with OV772x now successfully probing
