Simon Glass e46e4d6fd7 sandbox: efi_loader: Correct use of addresses as pointers
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.
