radeon/vce:Add support for frame_cropping_flag of VAEncSequenceParameterBufferH264

Browse source 
This patch will add support for frame_cropping when the input size is not
matched with aligned size. Currently vaapi driver ignores frame cropping
values provided by client. This change will update SPS nalu with proper
cropping values.

v2: Moving default crop setting to else when enc_frame_cropping_flag is not set.
