media: cec: seco: remove byte handling from smb_word_op
smb_word_op() has a parameter data_format that
determines if the data is either a byte or
word. From inspection, smb_word_op() is only
used by the macros smb_wr16() and smb_rd16()
both pass in CMD_WORD_DATA. There is no use of
smb_word_op() that passes in CMD_BYTE_DATA.
So remove the byte handling.
