[PATCH 05/15] mtd: spi-nor: Drop stale values

These apparently Micron-specific flash opcodes are used nowhere. They
are not exposed by a UAPI header either, so just drop them, they are
stale definitions.

I discovered them while working on Winbond VCR registers. For a
moment I thought VCR registers were wide spread (but, no).
