mb/google/rauru: Support new bias IC TPS65130RGER

Browse source 
The panel uses TPS65130RGER as the bias IC, with supply set to ±5.9V.
Configure TPS65130RGER initialization and power-on sequence according
to the tps65130.pdf.
The tps65132s driver is no longer used on this platform and remove it
from the build.

[INFO ]  mtk_display_init: 'BOE NS130069' 3504x2190@120Hz bpp 4

BUG=b:463911061
TEST=Check display initialization log and display are normal
BRANCH=none
