From: Nick Hawkins <nick.hawkins at hpe.com>

Add initial platform support for the HPE GSC ARM64 BMC SoC.

Changes since v5:
- Patch 3: Renamed GIC nodename from gic at ce000000 to interrupt-controller at ce000000
  (Krzysztof Kozlowski)
- Patch 3: Added Reviewed-by from Krzysztof Kozlowski
- Patch 4: Added Reviewed-by from Krzysztof Kozlowski

Changes since v4:
- All patches: Removed duplicate From: field in commit message body

Changes since v3:
- Patch 1: Moved GSC entry before GXP in hpe,gxp.yaml to maintain
  alphabetical ordering by fallback compatible (Krzysztof Kozlowski)
- Patch 2: Added Reviewed-by from Krzysztof Kozlowski
- Patch 3: Changed SPDX in gsc-dl340gen12.dts from GPL-2.0-only to
  GPL-2.0 to be consistent with gsc.dtsi (Krzysztof Kozlowski);
  reordered nodes within soc by ascending unit-address, placing UARTs
  before GIC per DTS coding style (Krzysztof Kozlowski);
  moved interrupt-parent before interrupts in timer and all UART nodes
  per DTS coding style (Krzysztof Kozlowski);
  reordered root-level nodes alphabetically: clock-33333333 before cpus
  before timer per DTS coding style (Krzysztof Kozlowski);
  reordered properties within all nodes to follow DTS coding style:
  compatible, reg first, then remaining alphabetically (Krzysztof
  Kozlowski)
- Patch 4: New patch adding CONFIG_ARCH_HPE=y to arm64 defconfig
  (Krzysztof Kozlowski)

Changes since v2:
- Patch 1: Removed separate ARM64/HPE GSC MAINTAINERS entry; instead
  renamed existing ARM/HPE GXP to ARM/HPE GXP/GSC and added arm64 DTS
  path there (Conor Dooley)
- Patch 2: Replaced menuconfig ARCH_HPE + nested ARCH_HPE_GSC with a
  single config ARCH_HPE; removed extra blank line (Krzysztof Kozlowski)
- Patch 3: Dropped clocks wrapper node, renamed fixed clock to
  clock-33333333; renamed ahb bus node to soc; reordered UART nodes by
  address for DTS coding style; replaced raw interrupt triplets with
  GIC_SPI/IRQ_TYPE_LEVEL_HIGH defines (Krzysztof Kozlowski)
