[PATCH] omap2: fix DPLL_FREQSEL calculation

[John Ogness]

Hi,

This patch fixes the calculation of the internal frequency. The value
of "n" is one less than the actual divider. 0 is a valid value.

An example where the internal frequency is calculated correctly can be
found here: clkt_dpll.c:_dpll_test_fint()

This patch is against linux-next-20110120.
