Adding IPU clock query functions for i.MX31 and i.MX35
(used to generate their LCD timing).
BTW: All functions are declared with the 'ulong' return type, but some are
defined with 'unsigned long'. And yes, its the same, but IMHO one type should
be used for all.

We need this function for MX35 support since the uart clock is not
equal to perclk1 anymore. Uh, it's really time to implement some
real clock API instead of this cruft.
