Subject: [PATCH v4 14/16] mtd: spi-nor: expose spi_nor_default_setup() in core.h

Flashes might want to add a custom setup hook to configure the flash in
the proper mode for operation. But after that, they would still want to
run the default setup hook because it selects the read, program, and
erase operations. Since there is little point in repeating all that
code, expose the spi_nor_default_setup() in core.h to
manufacturer-specific files.
