[ARM] 4418/1: AT91: Number of programmable clocks differs

The number of programmable clocks available on the AT91 processors can
differ, therefore do not always display the contents of the PMC_PCKR(0)
.. PMC_PCKR(3) registers (ie, assume there are 4 clocks).

If CONFIG_AT91_PROGRAMMABLE_CLOCKS is enabled, the programmable clocks
will be registered like the other system/peripheral clocks, and the
state of the programmable clocks will be displayed like with the other
clocks.
