mtd: spi: spi-nor-core: Add SST vendor specific SFDP parser
JESD216 allow vendors to define their own SFDP tables.
Add SST SFDP parser. The vendor table is allocated using resource-managed
kmalloc - the table will be freed on driver detach. It will be accessible
by getting the UCLASS_SPI_FLASH's private data.
The SST's SFDP table is particularly of interest because contains
pre-programmed globally unique EUI-48 and EUI-64 identifiers.
