gpio: of: Check propname before applying "cs-gpios" quirks
[ Upstream commit e5545c94e43b8f6599ffc01df8d1aedf18ee912a ]
SPI GPIO device has more than just "cs-gpio" property in its node and
would request those GPIOs as a part of its initialization. To avoid
applying CS-specific quirk to all of them add a check to make sure
that propname is "cs-gpios".
