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.

The sequences of configure_display() are similar on MediaTek platforms.
The sequences usually involve following steps:
1. Setup mtcmos for display hardware block.
- mtcmos_display_power_on()
- mtcmos_protect_display_bus()
2. Configure backlight pins
3. Power on the panel
- It also powers on the bridge in MIPI DSI to eDP case.
4. General initialization for DDP(display data path)
5. Initialize eDP/MIPI DSI accordingly,
- For eDP path, it calls mtk_edp_init() to get edid from the panel
and initializes eDP driver.
- For MIPI DSI path, the edid is retrieved either from the bridge or
from CBFS (the serializable data), and then initializes DSI driver.
6. Set framebuffer bits per pixel
7. Setup DDP mode
8. Setup panel orientation
This patch extracts geralt/display.c to mediatek/common/display.c and
refactors `struct panel_description` to generalize the display init
sequences. configure_display() is also renamed to mtk_display_init().

These backlight related functions can be reused in other variants, move
them out to the panel.c. Also the panel_geralt.c should be used for
Geralt, enable it on Geralt board only.

Based on the power sequence of the panel [1], the power on T2 sequence
VSP to VSN should be larger than 1ms, and the power off T2 sequence VSP
to VSN should be larger than 0ms. We modify the power sequence to meet
the datasheet requirement.

For Geralt, we use BOE_TV110C9M_LL0 as MIPI firmware display, so add the
power-on sequence for BOE_TV110C9M_LL0.

There are two ways to control backlight in geralt:
1. MIPI/eDP panel => control backlight via the GPIOs.
(`backlight chip enable` and `PWM dimming control`)
2. eDP OLED panel => enable backlight via `backlight chip enable` and
control dimming over AUX.
For MIPI/eDP panels(#1), both "backlight enable" and "PWM control" GPIOs
will be passed from coreboot. For eDP OLED panel(#2), only the
"backlight enable" GPIO will be passed. If depthcharge successfully gets
the GPIOs, it will use them to control backlight.

There are eDP and MIPI panels supported in geralt. We put the panels'
specified functions - `power_on()` and `configure_panel_backlight()` in
panel_geralt.c. Also provide the common interface `get_active_panel()`
in panel.c to generalize the display initialization. Since each board
may support a different set of MIPI panels, we put the MIPI data in a
separate file panel_geralt.c.
