Matt Coster fffc3866fe pvr: Support clear colours with more than 32 bits
The support for this seems to already exist, but was blocked by a
conditional. Replace with an assert to ensure the format can be packed
into 4x32 bit words (true for all currently supported formats).

When no flags are set, submit_info->flags is uninitialized. This is not

Karmjit Mahil 6a9364f4bc pvr: Change pvr_get_hw_clear_color() to pack based on accum formats.
`pvr_get_hw_clear_color()` now packs formats based on the accum
format which is how the hw deals with the formats internally and
might not line up exactly with the vk format representation.

E.g. R5G6B5_UNORM_PACK16 uses the U8 accum format so the USC will
internally use 3 bytes (1 per component) to deal with it instead
of 2 bytes which the vk format specifies. On USC EMITPIX, the PBE
will pack the results to 2 bytes using PACKMODE_R5G6B5 resulting
in the final value being in the vk format representation.
