Replace the hardcoded addresses for accessing the SYSC PM domain
registers by register offsets, relative to the SYSC base address stored
in struct rmobile_pm_domain.
In the future, the SYSC base address will come from DT.

Add support for the A3SM power domain, and hook it up as a subdomain of
A4S.
This domain contains the System CPU (Cortex-A9) hardware block. Hence
move the special CPU handling from A4S to A3SM.

Add support for the D4 power domain.
This domain contains the Coresight-ETM hardware block.
As long as the ARM debug/perf code doesn't use resource management with
runtime PM support, the D4 power domain must be kept powered to avoid a
crash during resume from s2ram (dbg_cpu_pm_notify() calls
reset_ctrl_regs() unconditionally, causing an undefined instruction
oops).

New and updated SoC support. Among the things new for this release are:
- at91: Added support for the new SAMA5D4 SoC, following the earlier SAMA5D3
- bcm: Added support for BCM63XX family of DSL SoCs
- hisi: Added support for HiP04 server-class SoC
- meson: Initial support for the Amlogic Meson6 (aka 8726MX) platform
- shmobile: added support for new r8a7794 (R-Car E2) automotive SoC
Noteworthy changes to existing SoC support are:
- imx: convert i.MX1 to device tree
- omap: lots of power management work
- omap: base support to enable moving to standard UART driver
- shmobile: lots of progress for multiplatform support, still ongoing
