gpio: of: Check for "spi-cs-high" in child instead of parent node

ndreys · linusw · commit 7ce40277bf84 · 2019-03-28T17:10:20.000+01:00
"spi-cs-high" is going to be specified in child node of an SPI
controller's representing attached SPI device, so change the code to
look for it there, instead of checking parent node.
