libpayload: Pass panel power-off commands to payloads

Browse source 
Introduce the lb_panel_poweroff/cb_panel_poweroff structs to pass the
panel power-off commands from coreboot to payloads.

Also add mipi_panel_parse_commands() to libpayload libc, so that
payloads can utilize it to parse the power-off commands.
