mb/google/nissa/var/anraggar: Tune eMMC DLL values
Anraggar cannot boot into OS and kernel loading failure. Update eMMC DLL values to improve initialization reliability - Sending different speed TX/RX command/data signal to eMMC and check the response is success or not. - Collecting every eMMC that use for the project - Based on above result to provide a fine tune DLL values BUG=b:308366637 TEST=Cold reboot stress test over 2500 cycles Change-Id: I9ec3cc23000301aa72aed96e74b63114623c4fc2 Signed-off-by: Simon Yang <simon1.yang@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/78851 Reviewed-by: Subrata Banik <subratabanik@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Eric Lai <ericllai@google.com>
