[PATCH] staging: fbtft: clarify TODO comment in fbtft-core

[Sachin Kumar <sachinkumar905846@gmail.com>]

Improve wording of a TODO comment to better describe the
intended optimization. The comment now clearly states that
only the changed display area should be updated instead of
refreshing the entire screen.
