[PATCH] ARM: omap1: clock: return 0 upon error from clk_round_rate()

[Paul Walmsley]

clk_round_rate() should return 0 upon an error, rather than
returning a negative error code.  This is because clk_round_rate() is
being changed to return an unsigned return value rather than a signed
value, since some clock sources can generate rates higher than
(2^31)-1 Hz.
