p0_mode set to one of the supported serial mode should not prevent
configuring the external SMI interface in
mv88e6xxx_g2_scratch_gpio_set_smi. 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.
