Subject: [PATCH v2 29/52] m68k: mac: Remove unused sine_data[]

When building with W=1:

    arch/m68k/mac/macboing.c:29:26: warning: ‘sine_data’ defined but not used [-Wunused-const-variable=]
       29 | static const signed char sine_data[] = {
	  |                          ^~~~~~~~~

The predefined sine table was superseded by a table calculated at
run-time in v2.2.0.
