soc/mediatek/mt8173: mt6391: vcore sleep voltage should be 0.7V 

Vcore voltage should be 0.7V during system suspend. Because data sheet of mt6391
was not correct, need to config to 0x0 instead of 0x1.

QI_VCORE_VSLEEP
00: 0.7V
01: 0.6V
10: 0.65V
11: 0.75V

BUG=chrome-os-partner:52719
TEST=powerd_dbus_suspend
