[PATCH v2 3/3] ARM: rockchip: initialize PBL malloc

[Sascha Hauer <s.hauer@pengutronix.de>]

Rockchip uses compressed firmware binaries. Depending on the compression
algorithm we might use early malloc space for decompressing. Initialize
the PBL malloc space to the memory end to make pbl_malloc() work. This
memory area will be overwritten later in barebox_pbl_start(), but it's
ok as the memory is only needed during decompression of the firmware
files.
