asm-generic: updates for 6.18

Two small patches for the asm-generic header files: Varad Gautam improves
the MMIO tracing to be faster when the tracepoints are built into the
kernel but disabled, while Qi Xi updates the DO_ONCE logic so that
clearing the WARN_ONCE() flags does not change the other DO_ONCE users.

Varad Gautam (1):
      asm-generic/io.h: Skip trace helpers if rwmmio events are disabled
