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 Change-Id: I22f04fa21b542e21e88c46547779cfb55beb5c12 Signed-off-by: Shon Wang <shon.wang@quanta.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/62317 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: EricR Lai <ericr_lai@compal.corp-partner.google.com> Reviewed-by: YH Lin <yueherngl@google.com>
