platform: msm_shared: enable different panel configuration modes
Add support to specify multiple working configurations for a given
panel. Choose the default configuration through target specific oem panel
module. Add support to select non-default configuration, if supported by
given panel, through "fastboot oem select-display-panel". Add support to
convey selected lk config to kernel by modifying kernel command line.
Ex:
fastboot oem select-display-panel nt35597_wqxga_dsc_video
fastboot oem select-display-panel nt35597_wqxga_dsc_video:cfg[0..2]
fastboot oem select-display-panel nt35597_wqxga_dsc_video:cfg[0..2]#sim
fastboot oem select-display-panel nt35597_wqxga_dsc_cmd
fastboot oem select-display-panel nt35597_wqxga_dsc_cmd:cfg[0..2]
fastboot oem select-display-panel nt35597_wqxga_dsc_cmd:cfg[0..2]#sim
