This approximately triples write performance for the SD card. My card
is too full of important data to collect very reliable numbers, but I
see 271.361% +/- 166.742% improvement (n=3 before, 6 after), for 'dd
if=/dev/zero of=/boot/asdf bs=1M count=3 oflag=dsync,direct'. Read
performance appears to be unaffected.

The power domain driver we've enabled doesn't actually do anything
without it, and we need it to do its job for VC4 to initialize
successfully.

Combined with the queued DT changes, we now get HDMI and 3D support.

This is also present in multi_v7_defconfig, and means that I can test
the pi1 with the 2835 defconfig in my normal environment.

Do we need to disable that too, or does hand-off from simplefb to the
accelerated driver work fine?
