ARM/dt: hammerhead: Reduce minimum panel brightness

Default minimum brightness is a tad too high, this change makes reading
in a dark environment much more enjoyable. A value of 3 is still within
the valid range (see lm3630 blmap).

msm: ocmem: Add macro and region size information to ocmem region

Some targets support half sized macros in the last region. Previously,
for these regions, only half the macros were turned on, and the clients
could not access memory. Read the hardware register to check if the
target supports half sized macros and update the calculation to switch
memory power states.

irq: Set CPU affinity right on thread creation

As irq_thread_check_affinity is called ONLY inside the while loop in
the irq thread, the core affinity is set only when an interrupt
occurs. This patch sets the core affinity right after the irq thread
is created and before it waits for interrupts. In real-tiime targets
that do not typically change the core affinity of irqs during
run-time, this patch will save additional latency of an irq thread in
setting the core affinity during the first interrupt occurrence for
that irq.
