tau32-ddk.c: suppress warning about ignored attributes

2024-04-20T10:29:10+00:00

This driver is heavily obfuscated, and causes a -Werror warning with
clang 18 now:

  sys/dev/ce/tau32-ddk.c:358:10: error: 'const' attribute on function returning 'void'; attribute ignored [-Werror,-Wignored-attributes]
    358 | ((const))nvqbt(void){__asm __volatile("repe; nop; repe; nop;"
        |          ^

Supress the warning since the driver can never be fixed. Direct commit
to stable/13, since the driver has been removed in 14.x and later.

These are false positives, since some of the driver source has been
deliberately obfuscated.

CWARNFALGS.$file centrally so we don't have to have it in all the
places. Remove a few warning flags that are no longer needed.
Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.

For sys/dev/ce/tau32-ddk.c, disable the following warning when building

with clang:

sys/dev/ce/tau32-ddk.c:1228:37: warning: implicit truncation from 'int' to bitfield changes value from 65532 to 8188 [-Wconstant-conversion]

Since this file is obfuscated C, we can never determine (in a sane way,
at least :) if this points to a real problem or not.  The driver has
been in the tree for more than five years, so it most likely isn't.
