arm64: allwinner: add BananaPi-M64 support

Browse Source 
The Banana Pi M64 board is a typical single board computer based on the
Allwinner A64 SoC. Aside from the usual peripherals it features eMMC
storage, which is connected to the 8-bit capable SDHC2 controller.
Also it has a soldered WiFi/Bluetooth chip, so we enable UART1 and SDHC1
as those two interfaces are connected to it.
