These nodes were sorted by name, but it's nice to have the same class of
devices together. As such, drop the pmu suffix and add "pmu" as a prefix.
This keeps consistency between other Exynos SoCs too.

CMU_PERIS is a new clock controller that clocks the MCT. The MCT has 9
timers (1x count-up global timer, 8x count-down CPU local).
The global timer generates 4 interrupts, and each local timer
generates one interrupt. So, in total 12 interrupts.

Since we have a PMU compatiable for Samsung's Mongoose cores now, drop
the comment that explains the lack of it and define the node.

Add PMU syscon, and syscon-reboot nodes to the Exynos990 dtsi.
Reboot of the Exynos990 SoC is handled by setting bit(SWRESET_TRIGGER[1])
of SWRESET register (PMU + 0x3a00).
Tested using the "reboot" command.

The Exynos 990 SoC is an ARMv8 mobile SoC found in Samsung Galaxy N/S20
series phones (x1sxxx, c1sxxx). Add minimal support for this SoC,
including:
- All 8 cores via PSCI
- ChipID
- Generic timer.
- Pinctrl
The devices using this SoC suffer from the same issue as Exynos 8895
caused by the stock Samsung bootloader, as it doesn't configure
CNTFRQ_EL0. Hence it's needed to hardcode the adequate frequency in the
timer node, otherwise the kernel panics.
