mtd: spi-nor-core: Adding different type of command extension in Soft Reset
Power-on-Reset is a method to restore flash back to 1S-1S-1S mode from 8D-8D-8D
in the begging of probe.
Command extension type is not standardized across flash vendors in DTR mode.
For suiting different vendor flash devices, adding a flag to seperate types for
soft reset on boot.
