[PATCH 4/5] OMAP clock: make the fixed divisor clock code available for all OMAPs

[paul@pwsan.com (Paul Walmsley)]

One of the OMAP1 clocks can use the fixed divisor recalculation code
introduced in the OMAP2 clock code, so rename the
omap2_fixed_divisor_recalc() function to omap_fixed_divisor_recalc()
and make it available to all OMAPs.  A followup patch converts the OMAP1
clock.
