radeon/vcn: Bitrate not updated when changing framerate

Browse source 
Issue: Encoding parameters not updated after changing FrameRate

Root Cause:
In radeon_enc_begin_frame, there is a parameter need_rate_control
which was enabled only if the bitrate is changed. Due to this the
radeon_enc_rc_layer_init was not updating the encoder parameters with new
framerate, peak_bits_per_picture_integer and avg_target_bits_per_picture

Fix:
Added the condition where we will check if there is a change in
other parameters and enable rate control. Eventually updating the
encoder parameters with new framerate and bitrate.
