Hi Ryan,

There's been a few cases where I've needed to set the rate of a fixed clock 
during boot - for example when a clock rate varies between boards, it may be 
defined in a platform-wide file, but have the rate modified early (ie, 
clk_foo.rate = 32678) in a board file.

Also, if we're parsing clocks from the device tree (or any other discovery 
mechanism), we'll need to modify rate.

Cheers,
