arm: imx-common: introduce back usec2ticks

This commit "2bb014820c49a63902103bac710bc86b5772e843"
do some clean up to use the code in lib/time.c.
But usec2ticks is still being used by security related job ring code.
Bring back the function to avoid build break when CONFIG_FSL_CAAM
is defined.
The computation logic has been changed, using 64-bit variable
to ease the process, making it work on older (MX5) platforms.
