From: Nick Hawkins <nick.hawkins@xxxxxxx>

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

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)

dt-bindings: arm: hpe,gxp: Add HPE GSC platform compatible
arm64: Kconfig: Add ARCH_HPE platform
arm64: dts: hpe: Add HPE GSC SoC and DL340 Gen12 board DTS
