media: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

media: vsp1: Add underrun debug print

Print underrun interrupts with ratelimited print.

Note that we don't enable the underrun interrupt. If we have underruns,
we don't want to get flooded with interrupts about them. It's enough to
see that an underrun happened at the end of a frame.

media: vsp1_drv: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

media: renesas: vsp1: Change V3U to be gen4

V3U is actually gen4, not gen3. The same IP is also used in the
(not-yet-supported) V4H.

Change VI6_IP_VERSION_MODEL_VSPD_V3U to VI6_IP_VERSION_MODEL_VSPD_GEN4,
to represent the model correctly. V3U and V4H can still be
differentiated, if needed, with the VI6_IP_VERSION_SOC_xxx.

Also mark VI6_IP_VERSION_MODEL_VSPD_GEN4 as gen 4 in vsp1_device_info,
and update the code to correctly match for gen 4.

media: renesas: vsp1: Add support for RZ/G2L VSPD

The RZ/G2L VSPD provides a single VSPD instance. It has the following
sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF.

The VSPD block on RZ/G2L SoCs does not have a version register, so
added a new compatible string "renesas,r9a07g044-vsp2" with a data
pointer containing the info structure. Also the reset line is shared
with the DU module.

media: renesas: vsp1: Add VSP1_HAS_NON_ZERO_LBA feature bit

As per HW manual V3M and RZ/G2L SoCs has nonzero LIF buffer
attributes. So, introduce a feature bit for handling the same.

This patch also adds separate device info structure for V3M and V3H
SoCs, as both these SoCs share the same model ID, but V3H does not
have VSP1_HAS_NON_ZERO_LBA feature bit.
