mb/google/hatch: Enable SD card support for hatch
Enable support for SD card support for hatch 1. Enable PCI device for SD and also configure SD detect GPIO 2. Configure SD card related GPIOs in gpio.c BUG=b:120914069 BRANCH=none TEST=Verify GPIO configuration with schematics Change-Id: I8ccaa28323b1e1fcc192e245347a96309227660b Signed-off-by: Maulik V Vaghela <maulik.v.vaghela@intel.com> Reviewed-on: https://review.coreboot.org/c/30545 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aamir Bohra <aamir.bohra@intel.com> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Subrata Banik <subrata.banik@intel.com>
