The _compatible argument of FBTFT_SPI_DRIVER() is never used in the
macro body. The device tree match table is created separately by
FBTFT_DT_TABLE() in both callers, FBTFT_REGISTER_DRIVER() and
FBTFT_REGISTER_SPI_DRIVER().
Drop the argument and update both callers. No functional change.
The argument has been unused since the macro was introduced in commit
c222ea5d2f33 ("staging: fbtft: Deduplicate driver registration macros").
Found with checkpatch.pl (MACRO_ARG_UNUSED). The change was prepared
with the help of an AI coding assistant (Claude); I reviewed it and
build-tested all fbtft drivers with W=1.
