The current masking of the p0_mode only checks the first 2 bits. This results in switches supporting serial mode cannot setup external SMI on certain serial modes (Ex: 1000BASE-X and SGMII). Extend the mask of the p0_mode to include the reduced modes and serial modes as allowed modes for the external SMI interface.
