This patch extracts some chunks from spi_nor_init_params and spi_nor_scan() and moves them into a new spi_nor_init() function. Indeed, spi_nor_init() regroups all the required SPI flash commands to be sent to the SPI flash memory before performing any runtime operations (Fast Read, Page Program, Sector Erase, ...). Hence spi_nor_init(): 1) removes the flash protection if applicable for certain vendors. 2) sets the Quad Enable bit, if needed, before using Quad SPI protocols. 3) makes the memory enter its (stateful) 4-byte address mode, if needed, for SPI flash memory > 128Mbits not supporting the 4-byte address instruction set. spi_nor_scan() now ends by calling spi_nor_init() once the probe phase has completed. Further patches could also use spi_nor_init() to implement the mtd->_resume() handler for the spi-nor framework.
