coresight: sequence FFCR writes during __etb_disable

Instead of writing FFCR bits 12 and 6 at once, sequence them i.e.
write bit 12 first to set ETB to stop on flush and followed by
setting bit 6 to trigger manual flush.

This should avoid any possible race between flush completing
before bit 12 getting set.
