net: airoha: Remove PCE_MC_EN_MASK bit in REG_FE_PCE_CFG configuration
PCE_MC_EN_MASK bit in REG_FE_PCE_CFG configuration performed in
airoha_fe_init() is used to duplicate multicast packets and send a copy
to the CPU when the traffic is offloaded. This is necessary just if
it is requested by the user. Disable multicast packets duplication by
default.
