MLK-19131 configs: imx8mm_evk: add jailhouse boot command
Add jailhouse env. Currently need to pass clk_ignore_unused to bootargs
to avoid linux root cell shutdown clocks used by inmates.
If only want a minimal clk being on in inmates, the clks could
be added in clk_inits_on in linux kernel drivers/clk/imx/clk-imx8mm.c
or use init-on-array under clk node.
