Some wifi cards need reset asserted until after the power supplies
have been enabled.
So wire up the W_DISABLE signal for the SDIO port (WIFI_REG_ON net) and
the BT_REG_ON net to use it for power sequencing.

This is needed for the 1LV Cyress WiFi module to probe correctly.
It also helps improve GNSS sensitivity.
