[PATCH v2 4/7] media: iris: add VPU5x internal buffer size calculations

[Wangao Wang <wangao.wang@oss.qualcomm.com>]

VPU5x firmware uses internal buffer formulas that differ from VPU4x. In
particular, the H.265 decoder persistent buffer needs space for SEI
unregistered userdata and three-dimensional userdata, and the encoder
calculations use a larger lambda LUT size.

Add a VPU5x buffer-size dispatcher and a VPU5x-specific H.265 persistent
buffer calculation while reusing the existing helpers for buffer types
whose formulas are unchanged.
