arm64: dts: ti: k3-am6xx-phycore-qspi-nor: Add overlay to enable QSPI NOR
Add an overlay to change from the default OSPI NOR to QSPI NOR
for all am6xx-phycore-som boards.
The EEPROM on am6xx-phycore-soms contains information about the
configuration of the SOM. The standard configuration of the SOM
has an ospi nor, but if qspi nor is populated, the EEPROM will
indicate that change and we can use this overlay to cleanly change to
qspi nor.
