gpio: of: Check propname before applying "cs-gpios" quirks

ndreys · linusw · commit e5545c94e43b · 2019-03-28T17:06:58.000+01:00
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".
