[PATCH v4] media: rkvdec: Drop unneeded per_request driver-specific control flag

[Ezequiel Garcia]

Currently, the drivers makes no distinction between per_request
and mandatory, as both are used in the same request validate check.

The driver only cares to know if a given control is
required to be part of a request, so only one flag is needed.

v4:
* Drop 'mandatory' from DECODE_MODE and START_MODE.
