The ColdFire DMA Timer hardware module is used on a number of the ColdFire

so that it can be used on any of those devices.

Acquire the SoC clock when using the DMA timer hardware module. With the
clock acquired we can enable it and get it ticking. On most ColdFire SoC
hardware the DMA timer clock is not enabled by default.

53xx and 5441x families of ColdFire SoC. Use it as clock source on those
parts to give a more accurate clock.

Hi Greg,
I was able to to test this on 528x and 5441x and didnt have problems, so you
can add my Acked-by if you want.
