mb/google/coral: add usb2 phy setting override for some variants
Due to there are some chances USB devices can not be detected. USB2 port#1 and #4 PHY register need to be overridden for variants Santa/Lava/Blue/Bruce/Astronaut. port#1: PERPORTPETXISET = 4 PERPORTTXISET = 4 IUSBTXEMPHASISEN= 1 PERPORTTXPEHALF= 0 port#4: PERPORTPETXISET = 7 PERPORTTXISET = 7 IUSBTXEMPHASISEN= 1 PERPORTTXPEHALF= 0 BUG=b:72623892 BRANCH=master TEST=emerge-coral coreboot chromeos-bootimage Change-Id: I401905685cc3078df657919b162272c3de320296 Signed-off-by: Pan Sheng-Liang <Sheng-Liang.Pan@quantatw.com> Reviewed-on: https://review.coreboot.org/23881 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
