Merge patch series "auxdisplay: charlcd: Refactor memory allocation"

Andy Shevchenko says:

The users of charlcd_alloc() call for additional memory allocation.
We may do it at the time of the main call as many other APIs do.
For this partially revert the change that brought us to the current
state of affairs, and refactor the code based on the original implementation.
