[U-Boot] [PATCH v5 37/41] rockchip: Add config_distro_bootcmd support

[Simon Glass]

From: Sjoerd Simons <sjoerd.simons at collabora.co.uk>

Now that MMC works in U-Boot add config distro command support to start
Linux in a standard fashion. One oddity here is that linux fails to load
when the fdt is relocated to above 512MB, so set fdt_high to make sure it's
loaded below that.
