mb/google/octopus: Fix wifi configuration
This change updates devicetree and GPIO configurations to match the
schematics:
1. pcie_rp...[2] is the one being used for wifi, thus, clk_req and
deemphasis_enable for [2] need to be set instead of [0].
2. WLAN power enable, wifi disable and PERST# GPIOs need to be
configured correctly.
BUG=b:76180142
TEST=Verified that wlan0 scan works.
