[v9,0/3] arm64: mvebu: Support for Marvell 98DX2530 (and variants)

This series adds support for the Marvell 98DX2530 SoC which is the Control and
Management CPU integrated into the AlleyCat5/AlleyCat5X series of Marvell
switches.

The CPU core is an ARM Cortex-A55 with neon, simd and crypto extensions.

This is fairly similar to the Armada-3700 SoC so most of the required
peripherals are already supported. This series adds a devicetree and pinctrl
driver for the SoC and the RD-AC5X-32G16HVG6HLG reference board.

The pinctrl changes from v4 have been picked up and are in linux-next so I
haven't included them in this round. That leaves just the dts files and a minor
Kconfig update for arm64.

Changes:

v9 (proposed by Marvell):
   It was discussed with Chris that Marvell will add some changes:
      1) Rename "armada-" prefix in dts(i) file names to ac5, because
         Armada has not much common with AC5 SoC.

      2) Add clock fixes:
         a) rename core_clock to cnm_clock

         b) remove axi_clock

         c) change cnm_clock to 325MHZ

         d) use cnm_clock for the UART
