To support the SPI MEM API, instead of modifying the existing U-Boot driver, this patch adds a port of the existing Linux driver. This also has the advantage that porting changes and fixes from Linux will be easier. Porting of driver left most of the functions unchanged while few of the changes are: -Remove lock(mutexes) and irq handler as u-boot is a single core execution. -Remove invalid masterid as it was required specially for multicore execution in LS2088ARDB which is not the case in u-boot. -Remove clock support as changing spi speed is not supported in uboot and nor in linux.
Currently tested on LS1088ARDB, LS1012ARDB, LS1046ARDB, LS1046AFRWY, LS1043AQDS, LS1021ATWR, LS2088ARDB, I.MX6ULL EVK.
