Hmm.. this "rmb" region is really:
0x0 PS_HOLD (write here to reset the chip, if the TZ lets you..)
..
0x8 SSCAON_CONFIG (essentially a syscon which you write to from your driver)
0xc SSCAON_STATUS (same)
But we've been describing things this way for years.. I don't know if it's
worth changing, especially since the rproc driver really assumes this to
be the case
