AGESA boards: Fix grammar in description of `OemCustomizeInitEarly`

The following command was used to correct the grammatical mistake.

    $ git grep -l 'This is the stub function will call' | xargs sed -i s,This is the stub function will call,This stub function will call, '{}'
    sed: -e Ausdruck #1, Zeichen 6: Nicht beendeter `s'-Befehl
