The commit b1b8f45b ("ARM: dts: bcm2837: Add missing GPIOs of Expander")
introduced a wifi power sequence. Unfortunately the polarity of the reset
GPIOs were wrong and broke the wifi support on Raspberry Pi 3 B and
later in 3 B+. This wasn't discovered before since the power sequence
takes only effect in case the relevant MMC driver is compiled as a module.

Fixes: b1b8f45b
