[PATCH v2 1/2] arm64: dts: a64-olinuxino: Enable RTL8723BS WiFi

[Jagan Teki]

Enable RTL8723BS WiFi chip on a64-olinuxino board:
- WiFi SDIO interface is connected to MMC1
- WiFi REG_ON pin connected to gpio PL2: attach to mmc-pwrseq
- WiFi HOST_WAKE pin connected to gpio PL3

[PATCH v2 2/2] arm64: allwinner: a64-sopine: Fix to use dcdc1 regulator instead of vcc3v3

[Jagan Teki]

Since current tree support AXP803 regulators,
replace fixed regulator vcc3v3 with AXP803 dcdc1 regulator where ever
it need to replace.

Tested mmc0 on sopine baseboard.
