To: u-boot
Current sf uses FAST_READ command, this patch adds support to
use the different/extended read command.
This implementation will determine the fastest command by taking
the supported commands from the flash and the controller, controller
is always been a priority.

This patch provides support to program a flash config register.
Configuration register contains the control bits used to configure
the different configurations and security features of a device.

This patch provides support to set the quad enable bit on flash.
quad enable bit needs to set before performing any quad IO
operations on respective SPI flashes.
Currently added set quad enable bit for winbond and spansion flash
devices. stmicro flash doesn't require to set as qeb is volatile.
remaining flash devices support will add in future patches.

Moved the flash params table from sf_probe.c and
placed on to sf_params.c, hence flash params file will
alter based on new addons.

Added macronix flash quad read/write commands support and
it's up to the respective controller driver usecase to
configure the respective commands by defining SPI RX/TX
operation modes from include/spi.h on the driver.
