[PATCH 2/2] ARM pbl: actually create cached mappings in the decompressor

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

We called create_sections with 4096MB as size argument, but create_sections
expected the argument in bytes, so create sections was completely optimized
away due to the size >>= 20. This patch changes the size argument to be in
megabytes and adjusts map_cachable to pass the argument in megabytes.
