mb/google/rex/{deku,karis}: Enable RTD3 for SSD
Deku S0ix is blocked by the SSD. Enable RTD3 for the SSD to unblock S0ix. RTD3 for SSDs has already been enabled on Rex and Screebo, too. To prevent this S0ix blocking issue, RTD3 should also be enabled for Karis. BUG=361011799 TEST=Run suspend_stress_test and check whether DUT can enter S0iX. suspend_stress_test w/o this CL (with Phison PCIE Gen4 SSD PSENN256GA87FC0) Suspend failed, s0ix count did not increment from 19182060 Substate Residency S0i2.0 0 S0i2.1 0 S0i2.2 0 And PC10 residency is only 60% (by SoCWatch) suspend_stress_test w/ this CL (with Phison PCIE Gen4 SSD PSENN256GA87FC0) Substate Residency S0i2.0 0 S0i2.1 19186 S0i2.2 3389654 And PC10 residency is ~90% (by SoCWatch) Change-Id: Iaded43a84ad1e245106d36a9d4aa83c40b046649 Signed-off-by: Curtis Chen <curtis.chen@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/84452 Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: Derek Huang <derekhuang@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
