[PATCH] staging: fbtft: fix space prohibited before that close parenthesis

[Eric LI <eric.lee0305@gmail.com>]

Clean up the following checkpatch error and warning in fbtft-bus.c.
drivers/staging/fbtft/fbtft-bus.c:14: WARNING: macros should not use a trailing semicolon
drivers/staging/fbtft/fbtft-bus.c:65: ERROR: space prohibited before that close parenthesis ')'
drivers/staging/fbtft/fbtft-bus.c:67: ERROR: space prohibited before that close parenthesis ')'

The reason of that error is the modifier argument is optional to the
macro define_fbtft_write_reg. So, even if removing the space before close
parenthesis, another error "space required after that ','" occurs.

In this fix, I change that modifier argument as optional, so that
it is both ok to use that macro with or without modifier argument.
