configs/orange-pi-zero-plus2: enable WiFi support

Orange-Pi Zero Plus2 board has AP6212 WiFi/BT combo, but does not have ethernet port. So it makes sense to enable wireless networking by default: - add DTS patch enabling AP6212 WiFi/BT combo support -- this patch is on its way to mainline Linux v4.16 - enable WiFi support in kernel config - enable Broadcom brcmfmac kernel driver in kernel config - add Broadcom wireless firmware package to image - add basic wireless tools to image - add mdev to image to enable module autoloading - add rootfs overlay with proper NVRAM file for on-board AP6212 chip Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

+Subject: [PATCH] arm64: dts: orange-pi-zero-plus2: enable AP6212a WiFi/BT combo
+
+Enable AP6212a WiFi/BT combo chip on orange-pi-zero-plus2 board:
+- WiFi SDIO interface is connected to MMC1
+- WiFi REG_ON pin connected to gpio PA9: attach to mmc-pwrseq
+- WiFi HOST_WAKE pin connected to gpio PL7
+- BT is connected to UART1
