Subject: [PATCH 00/11] Support Pensando Elba SoC

This series enables support for Pensando Elba SoC based platforms.
The Elba SoC has the following features:

- Sixteen ARM64 A72 cores
- Dual DDR 4/5 memory controllers
- 32 lanes of PCIe Gen3/4 to the Host
- Network interfaces: Dual 200GE, Quad 100GE, 50GE, 25GE, 10GE and
  also a single 1GE management port.
- Storage/crypto offloads and 144 programmable P4 cores.
- QSPI and EMMC for SoC storage
- Two SPI interfaces for peripheral management
- I2C bus for platform management

This is a respin based on review inputs.  The version of 
dtschema used is 2022.3.2.  Changes from V3:

0001-dt-bindings-arm-add-Pensando-boards.patch
- Add description and board compatible

0003-dt-bindings-mmc-Add-Pensando-Elba-SoC-binding.patch
- Change from elba-emmc to elba-sd4hc to match file convention
- Use minItems: 1 and maxItems: 2 to pass schema check

0005-dt-bindings-spi-dw-Add-Pensando-Elba-SoC-SPI-Control.patch
- Add required property pensando,syscon-spics to go with
  pensando,elba-spi

0006-MAINTAINERS-Add-entry-for-PENSANDO.patch
- Change Maintained to Supported

0007-arm64-Add-config-for-Pensando-SoC-platforms.patch
- Fix a typo on interface max speed

0008-spi-cadence-quadspi-Add-compatible-for-Pensando-Elba.patch
- Update due to spi-cadence-quadspi.c changes

0009-mmc-sdhci-cadence-Add-Pensando-Elba-SoC-support.patch
- Change from elba-emmc to elba-sd4hc to match file convention

0010-spi-dw-Add-support-for-Pensando-Elba-SoC.patch
- Use more descriptive dt property pensando,syscon-spics
- Minor changes from review input

0011-arm64-dts-Add-Pensando-Elba-SoC-support.patch
- Changed to dual copyright (GPL-2.0+ OR MIT)
- Minor changes from review input
