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.

I missed this part when looking at the EFI change.
