[Vikas Manocha]

This patchset adds support to get controller sram size from device tree, fix to
support different FIFO widths & adds dt binding doc.

Also this patchset enables cadence qspi controller for stv0991 soc, saves
environment in spi flash & moves CONFIG_OF in the defconfig file.

Changes in v4:
- Moved SPI configs in arch/arm/Kconfig
