media: atomisp_gmin_platform: Base CsiPort default on detected CLK

Browse source

On devices with 2 cameras and no _DSM / EFI-vars providing CsiPort
clock info, defaulting to CsiPort 0 obviously is wrong for 1 of the
2 cameras.

The Intel Cherry Trail (ISP2401) reference design combines:
 pmc_plt_clk_2 with CsiPort 0
 pmc_plt_clk_4 with CsiPort 1

The Intel Bay Trail (ISP2400) reference design combines:
 pmc_plt_clk_1 with CsiPort 0
 pmc_plt_clk_0 with CsiPort 1

Use this knowledge to set the default CsiPort value based on
the detected CLK for the sensor.
