efi_loader: adjust file system info

When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve
the file system info we claim that the volume is read only and has no free
space. This leads to failures in programs that check this information
before writing to the volume like SCT's InstallSct.efi.

Currently there is no function to determine these parameters in U-Boot. So
let's return optimistic values:

Return that the volume is writable.

Return the volume size as free space.
