[PATCH (net.git)] stmmac: fix PWRDWN into the PMT register for global unicast.

[Giuseppe Cavallaro]

MAC devices use the RWKPKTEN and MGKPKTEN bits of the PMT Control/Status
register to generate power management events.
So this patch is to properly set the RWKPKTEN [BIT(2)] inside the
PMT register (needed in case of global unicast).
