MLK-18793 imx8mq: config: add jailhouse env

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-imx8mq.c
