[PATCH V3] board: rockchip: add Powkiddy X55

From: Chris Morgan <macromorgan at hotmail.com>
The Powkiddy X55 is a Rockchip RK3566 based handheld gaming device.
UART, ADC, eMMC, and SDMMC are tested to work in U-Boot and this
successfully boots mainline Linux.
Kernel commit:
e99adc97e21a ("arm64: dts: rockchip: Add Powkiddy X55")
Signed-off-by: Chris Morgan <macromorgan at hotmail.com>
---
Changes since V2:
- Refactored to use the upstream device tree from Linux.
- Removed logic for handling the adc button and instead simply try to
boot from sdmmc0 as a valid target first.
