The cache-flush function is incorrect which causes a crash in the
remoteproc tests with arm64.

Fix both problems by using map_sysmem() to convert an address to a
pointer and map_to_sysmem() to convert a pointer to an address.

Also update the image-loader's cache-flushing logic.

Before executing code that we have loaded from a file we need to flush the
data cache and invalidate the instruction flash.

Implement functions flush_cache() and invalidate_icache_all().
