Subject: [PATCH 0/3] arm64: dts: meson: minor P212/VIM1 fixups

The P212 (S905X reference board) dts is used with a number of no-name
Android boxes that follow the reference design, and users had noticed
that BT worked but WiFi did not. While investigating and adding the
missing WiFi bits to the dtsi for testing I spotted that VIM1 inherits
from the p212 dtsi and has the BT node duplicated, so we can clean that
up too. And since we're tidying things, the pwm_ef node can be moved
to maintain normal alpha sorting.

Subject: [PATCH 1/3] arm64: dts: meson: add Broadcom WiFi to P212 dtsi

The P212 has a combined WiFi/BT module. The BT side is already enabled
in the dtsi but the WiFi side is not. Let's tweak SDIO speed (in-line
with other GXL/GXM devices) and enable the WiFi module.

Subject: [PATCH 3/3] arm64: dts: meson: remove Broadcom WiFi/BT nodes from Khadas VIM1

The Broadcom WiFi/BT SDIO nodes are now inherited from the P212 common dtsi
so we can remove them from the VIM1 board dts.

The SDIO freq is marked as 50000000 in the p212 DTSI and was explicitly changes
by Jerome in adc52bf7ef16 ("arm64: dts: meson: fix mmc v2 chips max frequencies")

The change is ok if you change the p212 DTSI to 100000000 aswell.
