Add SPI-NOR framework

SPI-NOR framework is based on SPI-MEM framework using
spi_mem_op execution interface.

It implements read functions and allows NOR configuration
up to quad mode.
Default management is 1 data line but it can be overridden
by platform.
It also includes specific quad mode configuration for
Spansion, Micron and Macronix memories.
