target: add support to skip panel configuration in LK
In the current implementation, a valid panel string can be
passed to kernel via command line argument only if the panel
is supported in LK. Add support to pass the panel string to kernel
even in cases where the panel is not supported in LK. Use a panel
lookup table to acquire the correct panel DT string to be passed to
kernel.
Default:
fastboot oem select-display-panel jdi_1080p_video
Skip panel:
fastboot oem select-display-panel jdi_1080p_video:skip
Disable continuous splash:
fastboot oem select-display-panel jdi_1080p_video:disable
