[PATCH v1 2/2] auxdisplay: charlcd: Provide a forward declaration

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

While there is no compilation error, strictly speaking compiler
should know about used types beforehand. Provide a forward decration
for struct charlcd_ops before using it in struct charlcd.
