rockchip: add Radxa ROCK 2A/F support
Hardware
--------
RockChip RK3528 ARM64 (4 cores)
1/2/4GB LPDDR4 RAM
1x LED (state)
1x Reset button
0/8/16/32/64GB eMMC on-board
Micro-SD Slot
PCIe FPC connector
3x USB 2.0 Port
HDMI/AV OUT
USB Type-C 5V Power
ROCK 2A:
+ 3.5mm audio out
+ 1000 Base-T
+ SYS LED
+ USB 3.0 Port (conflicts with PCIe)
Installation
------------
Uncompress the OpenWrt sysupgrade and write it to a micro SD card or
internal eMMC using dd.
