soc/mediatek: Add common implementation to configure display
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().
TEST=check FW screen on geralt.
