Mans Rullgard 9bc30ab821 auxdisplay: charlcd: fix x/y command parsing
The x/y command parsing has been broken since commit 129957069e
("staging: panel: Fixed checkpatch warning about simple_strtoul()").

Commit b34050fadb ("auxdisplay: charlcd: Fix and clean up handling of
x/y commands") fixed some problems by rewriting the parsing code,
but also broke things further by removing the check for a complete
command before attempting to parse it.  As a result, parsing is
terminated at the first x or y character.

This reinstates the check for a final semicolon.  Whereas the original
code use strchr(), this is wasteful seeing as the semicolon is always
at the end of the buffer.  Thus check this character directly instead.
