mlxsw: reg: Move 'mpsc' definition in 'mlxsw_reg_infos'

The array 'mlxsw_reg_infos' is ordered by registers' IDs. The ID of MPSC
register is 0x9080, so it should be after MCDA (register ID 0x9063) and
not after MTUTC (register ID 0x9055). Note that the register's fields are
defined in the correct place in the file, only the definition in
'mlxsw_reg_infos' is wrong. This issue was found while adding new
register which supposed to be before mpsc.
