MA-17788 Boot time refine for automotive

Disable unused dts and configs for imx8q to reduce the boot time.

The 'part_get_info_by_name' can be very time consuming as it will
loop through all the GPT entries to find the matched partition,
specify the number of 'misc' partition and use 'part_get_info' to
load the partition info directly will save much time.

With this patch, about 300ms can be save for imx8qm, about 350ms
can be saved for imx8qxp.

Test: boot tests.
