[U-Boot] [PATCH v2] sun50i: a64: Add initial Banana Pi M64 support

[Jagan Teki]

From: Jagan Teki <jagan@amarulasolutions.com>

BPI-M64 is a 64-bit quad-core mini single board computer
using the Allwinner A64 SOC.

BPI-M64 features
- 1.2 Ghz Quad-Core ARM Cortex A53
- 2GB DDR3 SDRAM with 733MHz
- MicroSD/eMMC(8GB)
- 10/100/1000Mbps ethernet (Realtek RTL8211E/D)
- Wifi + BT
- IR receiver
- Audio In/Out
- Video In/Out
- 5V 2A DC power-supply

For dts file,
Sync with Linux commit 4879b7ae("Merge tag 'dmaengine-4.12-rc1'").

Changes for v2:
- Update email-id
- Tested on BPI-M64
- Added MMC Slot 2 CONFIG_

Note:
Ethernet missing here, since the a64 emac as moved to sun50i-a64-pine64-plus-u-boot.dtsi
once it rename/move/update to shared dtsi BPI-M64 should have it, otherwise will
create emac node inside m64 dts.
