MLK-11080-2 bcmdhd: add WL_HOST_WAKEUP support
WL_HOST_WAKEUP can use outband GPIO interrupt instead of the standard
SDIO interrupt which can improve the WiFi performance a lot.
After enable WL_HOST_WAKE, the performance could increase about TX: 42% / RX: 26%.
Original:
Tx: 107 Mbits/sec Rx: 80.2 Mbits/sec
Now:
Tx: 152 Mbits/sec Rx: 101 Mbits/sec
