dev: gcdb: display: handle single DSI use-case on DSI-1 properly
In the current implementation, if we pass primary panel as "none", then
the gcdb cmdline argument is passed as the default value "0:dsi:0".
For single DSI case where the panel is supported on DSI-1 controller
and LK support is not available for the panel, we need to make sure
that the correct gcdb command line argument is passed to kernel.
This change takes care of it when the following fastboot oem command
is passed.
