docs: EFI configuration file must be ASCII type

Currently Xen can only read the configuration file if it is in ASCII
format. If it is in CHAR16 or CHAR8 it will choke. One way to verify
this is to use 'file':

xen.cfg:        ASCII text
xen-char16.cfg: Little-endian UTF-16 Unicode text, with CRLF, CR line terminators

The latter is no good.
