[coreboot-gerrit] Change in coreboot[master]: mb/google/dedede: Set the GPIO to EDGE_BOTH trigger for SD card CD pin

[Kaiyen Chang (Code Review)]

Hello build bot (Jenkins), Kaiyen Chang,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/48303

to look at the new patch set (#2).

mb/google/dedede: Set the GPIO to EDGE_BOTH trigger for SD card CD pin

The default setting of LEVEL/EDGE of GPIO is zero, which is LEVEL
trigger. So we need to set the GPIO to EDGE_BOTH trigger for SD card CD
pin in advance in coreboot to avoid the probabilistic interrupt storm
occuring during the period that kernel is configuring the GPIO for SD
card CD pin.

BUG=b:174336541
TEST=Run 1500 reboot iterations successfully
