On the Artik520 module, there's a bcm4354 attached to mshc_1. Enable
it, and turn on the regulator used for it, so that both wifi & bluetooth
work.
Verified to work on the Artik 520 evaluation board.
v2: accidentally sent out v1
v3: non-removable instead of broken-cd, alphabetical order, formatting
