35a4f89cd4 arm64: dts: zcu100-revC: Give wifi some time after power-on
Somewhere along recent changes to power control of the wl1831, power-on
became very unreliable on the Ultra96, failing like this:

wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16

After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms,
Ultra96 is already happy with 10 ms.

1696acf44e arm64: dts: zynqmp: replace gpio-key,wakeup with wakeup-source property
Most of the legacy "gpio-key,wakeup" boolean property is already
replaced with "wakeup-source". However few occurrences of old property
has popped up again, probably from the remnants in downstream trees.

This patch replaces the legacy properties with the unified
"wakeup-source" property introduced by:
"Input: gpio_keys - switch to using generic device properties"
