i.MX: Remove CCM useless clock computation handling.
Most clocks supported by the CCM are useless to the qemu framework.
Only clocks related to timers (EPIT, GPT, PWM, WATCHDOG, ...) are usefull
to QEMU code.
Therefore this patch removes clock computation handling for all clocks but:
* CLK_NONE,
* CLK_IPG,
* CLK_32k
