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.
