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

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.
