core: imx: re-work SoC version detection

Move DIGPROG_OFFSET to appropriate registers header files.
Store cpu type and SoC revision in global variables instead of

imx_digproc() now gets also the minor SoC revision.

ftrace: Add function execution time support

Add support to dump function execution time at corresponding function
exit points in output ftrace buffer.

To achieve proper function execution time we need to exclude TA suspend
time from timestamps, so add corresponding support in TEE core.

Also user mapping must be active to access ftrace buffer, so do that
during TA resume.
