0x3a00 is a reserved register as per the datasheet. The driver
currently sets to it 0x01 while the datasheet claims 0x00 to be
the default value.
On one of the setup based on i.MX8MP platform with IMX335, this register
write broke the CSI-2 configuration. Setting 0x3a00 to its default
value (i.e. 0x00) fixed the issue. It is not clear from the datasheet
what this register write is responsible for but setting it to its default
value seems the right thing to do, provided it has been found
responsible to break CSI-2 configuration on one of the platform.

The SYSTEM_CTRL0 register in ov5645 is almost similar to ov5640. But the
hard reset control is mandatory for the ov5645 device, so there is no
need for soft reset in the driver.
Add a 1msec delay for the software power up (OV5645_SYSTEM_CTRL0_START)
register in ov5645_global_init_setting. Without this delay sometimes the
image is not captured at all when the i2c frequency is 400kHz.
The changes are fixing both the greenish issue and image capture at 400kHz
i2c frequency on Renesas RZ/G2L SMARC EVK platforms.

req_fr check in alvium_s_frame_interval() is incorrect. In particular
req_fr can't be >=max and <= min at the same time. Ensure the requested
frame rate remains within the supported range between min_fr and max_fr by
clamping it.
Also remove the unused dft_fr argument of alvium_get_frame_interval().

Inline alvium_set_frame_interval() into alvium_s_frame_interval().
The alvium_set_frame_interval() is called once only, by
alvium_s_frame_interval(). The latter is a thin wrapper around the
former. Inline the function in its caller to make the code more
readable.

Menu controls that use the menu_skip_mask require that the min-max range is
inside 0-63.
Negative values obviously make no sense for menu controls, and the maximum
value is currently limited by the number of bits of the menu_skip_mask
value. However, if menu_skip_mask == 0, then larger menus are fine.
If we ever need to add support for larger menus that support the skip
mask, then more work is needed.
In the places where the menu_skip_mask is checked, use BIT_ULL to get the
bit to check and check if the bit number is < BITS_PER_LONG_LONG to avoid
shifting out of range. With the new check in check_range this should
never happen, but it is better to be safe and avoid static analyzer
warnings.

The rcar-csi2 driver was added before the platform/renesas directory
existed and since it was used together in a pipeline with the rcar-vin
driver it was located together with it.
The rcar-isp driver can also be used together with the rcar-csi2 driver
in a pipeline that is terminated by the rcar-vin driver. However by the
time rcar-isp was added the platform/renesas directory existed so it was
added there.
To remove the confusion that the rcar-csi2 driver have code dependencies
on the rcar-vin driver move it to the same directory level as the
rcar-isp driver. This makes it clear they are three distinct drivers
that can be used together in a pipeline, but do not depend on each
other.

Replace the old SET_RUNTIME_PM_OPS() helpers with its modern alternative
RUNTIME_PM_OPS(). The usage of pm_ptr and RUNTIME_PM_OPS() allows the
compiler to see where it's used but still drop the dead code. After this
we can get rid of the unnecessary '__maybe_unused' annotations on PM
functions.
