Add MIPI panel related GPIOs to lb_gpio so Depthcharge can manage panel
reset and power signals when needed.
The following GPIOs are added:
- panel_resx (GPIO_EN_PP3300_EDP_X)
- mipi_iovcc_en (GPIO_EN_PP6000_MIPI_DISP)
- mipi_tp_rstn (GPIO_TCHSCR_RST_1V8_L)
This allows Depthcharge to release reset and disable IOVCC in the
required order to meet the panel power-off timing specification.
