Add the Serial Flash Controller and it's pincontrols. Signed-off-by: Alex Bee <knaerzche@gmail.com> --- changes since v2: Fixed pinux settings for the chipselect pincontrols which originated from contradictory documentation: Datasheet [0] (page 29/31) says it is func4 (when start counting with func1), while TRM [1] (page 185) says func3 (register value 0x2). It turned out TRM is correct as with setting cs pincontrols to func4 the spi chip is not detected, while func3 is fine.
