sf: Add memory mapped read support
Qspi controller can have a memory mapped port which can be used for data read. Added support to enable memory mapped port read. This patch enables the following: - It enables exchange of memory map address between mtd and qspi through the introduction of "memory_map" flag. - Add support to communicate to the driver that memory mapped transfer is to be started through introduction of new flags like "SPI_XFER_MEM_MAP" and "SPI_XFER_MEM_MAP_END". This will enable the spi controller to do memory mapped configurations if required.
