Add AMD Pensando common and Elba SoC specific device nodes
Signed-off-by: Brad Larson <blarson@amd.com>

New series baseline:
- Remove references to system controller
Old series history:
v15 changes:
- The first cell in the cpu reg property is always zero. Change
address-cells to <1> and dropped the leading zero from all cpu* reg<>
- Added read-only and spare partitions to flash0
v14 changes:
- Fix dtbs_check l2-cache* property issue by adding required
cache-level and cache-unified properties
- Observed the issue after updating dtschema from 2023.1 to 2023.4
and yamllint from 1.26.3 to 1.30.0
v11 changes:
- Delete reset-names
- Fix spi0 compatible to be specific 'amd,pensando-elba-ctrl'
v9 changes:
- Single node for spi0 system-controller and squash
the reset-controller child into parent
