mb/google/volteer: Enable RTD3 for SD card
Enable the PCIe RTD3 driver for the PCIe attached SD card interface and provide the enable/reset GPIOs. These GPIOs are common across all variants so this is implemented in the baseboard devicetree with an fw_config probe if the device is present. The RTS5261 device does not have an enable GPIO so it is disabled in a workaround in mainboard.c, along with marking the SD-Express device as external. BUG=b:162289926, b:162289982 TEST=Tested on Delbin platform to ensure the system can enter the S0i3.2 substate and suspend/resume is stable. enabling this for the regular Genesys Change-Id: I40fe05829783c7bce2a2c4c1520a4a7430642e26 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/47377 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
