ARM: MXS: remove board specific clock setups 

Some boards have board specific special clock setups. These are now
done in the SoC specific clock drivers.

It is assumed that most board specific clock setup is done based on
copy/paste from U-Boot. The generalized clock setup differs from
some boards:

- ioclk are adjusted to 480MHz
- ssp clocks are adjusted to 96MHz
- enet out clock is enabled

Some boards adjusted the ioclk to 320MHz and the ssp clock to 160MHz.
