Arguments:
Val - pointer to the variable to store the value to
String - string that contains the value to parse and convert
EndIdx - index on which the parsing stopped. It points to the
first character that was not part of the returned Val.
It's valid only if the function returns success.
It's optional and it could be NULL.
Returns:
EFI_SUCCESS - if successful
EFI_INVALID_PARAMETER - if String is in unexpected format
