[PATCH 1/3] OMAP3 clock: Fix the DPLL freqsel computations

[Paul Walmsley]

From: Rajendra Nayak <rnayak at ti.com>

Fix the freqsel value computation. Use n instead of (n+1)

The formula in the TRM uses a zero-based N, hence the (n+1); however
at this point in the clock34xx.c code, N is one-based.

Hayati Bayrakdar <h-bayrakdar at ti.com> and Nishanth Menon <nm at ti.com> helped
track down this bug.
