[PATCH] display/disp_hcms29xx: Fix string truncation warning

[Aschref Ben-Thabet]

From: Aschref Ben Thabet <aschref.ben-thabet at embedded-brains.de>

Strncpy() is unsafe if the terminating NUL is missing. Replace it by the
safer strlcpy() and fix the string truncation warning,since the
strlcpy() function returns the total length of the string it tried to
create,that means: the length of src.
