Permit use of a udevice to talk to SPI flash. Ultimately we would like
to retire the use of 'struct spi_flash' for this purpose, so create the
new API for those who want to move to it.

Add a convenience function to access the private data that a uclass stores
for each of its devices. Convert over most existing uses for consistency
and to provide an example for others.

Add a driver model uclass for SPI flash which supports the common
operations (read, write, erase). Since we must keep support for the
non-dm interface, some modification of the spi_flash header is required.
CONFIG_DM_SPI_FLASH is used to enable driver model for SPI flash.
