ad9be163c5 media: chips-media: wave5: 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 ignored (apart
from emitting a warning) 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. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

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

prefix should not be included as it deviates from naming convention.

4e4103d6f3 media: chips-media: wave5: Fix panic on decoding DECODED_IDX_FLAG_SKIP
The display frame region information received from the vpu also
contains the frame display index: info->index_frame_display.

This index, being a s32, can be negative when a skip option is passed.
In that case, its value is DECODED_IDX_FLAG_SKIP (-2).

When disp_idx == -2, the following exception occurs:

15dfed5b49 media: chips-media: wave5: VIDEO_WAVE_VPU should depend on ARCH_K3
The Chips&Media Wave 5 Series multi-standard codec IP is currently only
supported on Texas Instruments K3 architecture.  Hence add a dependency on
ARCH_K3, to prevent asking the user about this driver when configuring a
kernel without Texas Instruments K3 Multicore SoC support.
