Some SDIO Wi-Fi chips (such as RTL8703AS) have a UART bluetooth, which
has a dedicated enable pin (PL8 in the reference design).

Enable the pin in the same way as the WLAN enable pins.

Tested on an A33 Q8 tablet with RTL8703AS.

This patch should be coupled with the uart1 node patch I send before:

For RTL8703AS, the rtl8723bs bluetooth code is used, which can be retrieve from:
