Adding IPU clock query functions for i.MX31 and i.MX35
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.
