feat(msm8916): setup hardware for non-secure world
Booting e.g. Linux in the non-secure world does not work with the
msm8916 port yet because essential hardware is not made available to
the non-secure world. Add more platform initialization to:
- Initialize the GICv2 and mark secure interrupts.
Only secure SGIs/PPIs so far. Override the GICD_PIDR2_GICV2
register address in platform_def.h to avoid a failing assert()
because of a (hardware) mistake in Qualcomm's GICv2 implementation.
- Make a timer frame available to the non-secure world.
The "Qualcomm Timer" (QTMR) implements the ARM generic timer
specification, so the standard defines (CNTACR_BASE etc)
can be used.
- Make parts of the "APCS" register region available to the
non-secure world, e.g. for CPU frequency control implemented
in Linux.
- Initialize a platform-specific register to route all SMMU context
bank interrupts to the non-secure interrupt pin, since all control
of the SMMUs is left up to the non-secure world for now.
