mb/google/geralt: Enable BOE_NV110WUM_L60 panel for Ciri

The MIPI panel BOE_NV110WUM_L60 will be used for Ciri, enable it.
Also remove the `mdelay(10)` after mtk_i2c_bus_init, because MTK
confirms this is not needed. Add mdelay(2) between VDD18 and VSP/VSN
to meet the panel datasheet.

BUG=b:308968270
TEST=Boot to firmware screen
BRANCH=None
