[PATCH 3/5] mtd: spi-nor: Move the SFDP header structure to a C header

The sfdp_header structure is currently defined in sfdp.c, whereas the
sfdp_parameter_header structure is defined in sfdp.h. In order to ease
the reuse of this structure outside of the sfdp.c file, move this
structure to the sfdp C header (.h).
