soundwire: cadence_master: add BRA_NumBytes[8] support
The header[0] bit definitions are:
Header[0] bits 7 – 6: BRA_HeaderType
Header[0] bits 5 – 2: BRA_DeviceAddress[3:0]
Header[0] bit 1 BRA_Opcode 1 => Write, 0 => Read
Header[0] bit 0 BRA_NumBytes[8]
And the header[1] indicates the BRA_NumBytes[7:0]. The existing code
doesn't handle BRA_NumBytes[8] therefore the maximum BRA number of a
frame is limited to 255.
Fixes: fe8a9cf75c1e ("soundwire: pass sdw_bpt_section to cdns BPT helpers")
