radeon/uvd: increase max height to 4096 for VI and newer

radeon/uvd: increase max height to 4096 for VI and newer

With this issue 'mpv --hwdec=vdpau --vo=vdpau <stream>' fails
for vdpau decode if the stream height is 4096. Vdpau decode of
height upto 4096 is necessary usecase on amdgpu driver for VI
and newer platforms.

The fix is in driver specific implementation of "Decoder
Query Capabilities" API to return 4096 for VI and newer
platforms. With this fix vdpauinfo reports height support as
4096 and mpv for vdpau decode works fine for 4096 height streams.
