[ARM] OMAP: Make dpll4_m4_ck programmable with clk_set_rate()

Filling the set_rate and round_rate fields of dpll4_m4_ck makes
this clock programmable through clk_set_rate().  This is needed
to give omapfb control over the dss1_alwon_fck rate.

This patch includes a fix from Tomi Valkeinen <tomi.valkeinen@nokia.com>.
