[XEN PATCH] efi: mechanical renaming to address MISRA C:2012 Rule 5.3

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

Rule 5.3 has the following headline:
"An identifier declared in an inner scope shall not hide an
identifier declared in an outer scope"

The function parameters renamed in this patch are hiding a variable defined
in an enclosing scope or a function identifier.

The following rename is made:
- s/cfg/config/
to distinguish from the variable 'cfg', which is hidden by the parameter inside
the modified functions.
