[PATCH v3 0/3] Read MAC Address from SST vendor specific SFDP region

[Manikandan Muralidharan <manikandan.m@microchip.com>]

This patch series adds support to parse the SFDP SST vendor map, read and
store the EUI-48 and EUI-64 Address (if its programmed) using the
resource-managed devm_kcalloc which will be freed on driver detach.
Register EUI addresses into NVMEM framework for the net drivers to access
them using nvmem properties.
This change ensures consistent and reliable MAC address retrieval
from QSPI benefiting boards like the sama5d27_wlsom1, sama5d29 curiosity
and sam9x75 curiosity.

--------
changes in v3:
- 2/3 - add support to update the QSPI partition into 'fixed-partition'
	binding in sama5d27_wlsom1
- 3/3 - add nvmem-layout in qspi node for EUI48 MAC Address and nvmem cell
	properties for macb node in sama5d27_wlsom1

changes in v2:
- 1/3 - parse the SST vendor table, read and store the addresses
	into a resource - managed space. Register the addresses
	into NVMEM framework
- 2/3 - add support to update the QSPI partition into 'fixed-partition'
	binding
