Add DT bindings to describe the rpm/rpmh power domains found on Qualcomm
Technologies, Inc. SoCs. These power domains communicate a performance
state to RPM/RPMh, which then translates it into corresponding voltage on a
PMIC rail.

This patch adds a regulator driver for the MCP16502 PMIC.
This drivers supports basic operations through the
regulator interface such as:
- setting/reading voltage
- setting/reading operating mode
- reading current status
- transitioning to/from suspend-to-ram and standby
power states

When running a kernel in qemu with enough debugging options (slub-debug,
ftrace, kcov, kasan, ubsan, ...) enabled together, that results in a
slow initcall. So a 'watchdog: BUG: soft lockup' happens:
[ 44.105619] Call trace:
[ 44.106709] __slab_alloc+0x70/0x88
[ 44.107757] kmem_cache_alloc
When option CONFIG_KASAN is enabled toghether with ftrace, function
ftrace_graph_caller() gets in to a recursion, via functions
kasan_check_read() and kasan_check_write().
Breakpoint 2, ftrace_graph_caller () at ../arch/arm64/kernel/entry-ftrace.S:179

Me neither. I would expect a pure userspace port, with limitations in
what ioctls you can use, and perhaps support from GCC to share more

These iommus should be associated with the device (i.e. the DSP itself).
