At present it is not possible to find out which part of the string is the number part and which is before it. Add a new variant which provides this feature, so we can separate the two in the caller.

Changes in v3:
Change the function to return a pointer to the first digit
Add some tests, including one for 'abc123def456'

- trailing_strtoln_end() - extract trailing integer from a fixed-length string
- Given a fixed-length string this finds a trailing number on the string
- and returns it. For example, "abc123" would return 123. Only the
- characters between @str and @end - 1 are examined. If @end is NULL, it is
- set to str + strlen(str).
- @str: String to exxamine
- @end: Pointer to end of string to examine, or NULL to use the
whole string
- @endp: If non-NULL, this is set to point to the character where the
- number starts, e.g. for "mmc0" this would be point to the '0'; if no
- trailing number is found, it is set to the end of the string
- @return training number if found, else -1

Yes I am slowly getting used to this.
Is there any way to accept both? U=Boot has used @return for years so there is lots of itin the code.
Can we just do a coccinelle script to just update the codebase?
