msm: vidc: align capabilities to 32 considering hevc

For hevc codec, LCU sizes are 32x32 or 64x64. Existing
capabilities consider alignment with 16. Considering a
hevc clip of dimension 4096x2160, the coded resolution
becomes 4096x2176. Limiting the cap with 4096x2160 will
break such usecase, hence keeping the capabilities
considering 32-byte alignment.
