[U-Boot] [PATCH v5 30/41] rockchip: Add basic support for firefly-rk3288

[Simon Glass <sjg@chromium.org>]

The Firefly RK3288 is a suitable target board for initial mainline Rockchip
support. It includes a good set of peripherals, a recent SoC and it is
readily available.

This adds only some basic files required to allow the baord to display a
serial message in SPL and hang.

---

Changes in v5:
- Drop CONFIG_ROCKCHIP_MMC from rk_common.h
- Drop CONFIG_SPL_LED_SUPPORT from header file and move to Kconfig
- Use CONFIG_ROCKCHIP_DWMMC instead of CONFIG_ROCKCHIP_MMC

Changes in v4:
- Adjust the defconfig file to suit mainline

Changes in v3:
- Make use of additional features since version 2

Changes in v2:
- Drop use of CONFIG_USE_PRIVATE_LIBGCC=y
- Tidy up license headers and remove SPL #ifdefs
