mb/google/brya/var/vell: Change to ELAN touchpanel driver

Disabled G2touch driver and add ELAN touchpanel driver for vell.
Due to incorrect BIOS setting, touch screen IC FW can't update and work.
According to ELAN's recommendations, we coreect the ELAN2513 driver's setting and change I2C address to 0x10

BUG=b:221340736
TEST=emerge-brya coreboot and can flash touch screen FW
