[PATCH] staging: fbtft: fix macro usage and style warnings

[DeepanshuPratik <deepanshu.pratik@gmail.com>]

This patch fixes the trailing comma issue in the
define_fbtft_write_reg() macro calls, which caused
checkpatch.pl to complain with:

  ERROR: space prohibited before that close parenthesis ')'

The affected macro invocations were updated to pass an
identity modifier instead of leaving the argument empty.
This resolves build errors while ensuring compliance
with kernel coding style.

No functional changes are introduced; this patch only
addresses build and style issues.
