mlxsw: reg: Increase Management Cable Info Access Register length

The layout of the register always supported 128 bytes payloads, but the
driver defined the register with a shorter length because it uses a
maximum payload size of 48 bytes. Increase the register's length in
preparation for using 128 bytes payloads.
