[PATCH 2/5] arm/mxc: add clk members to ease dt clock support

[Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

The 'rate' is added for fixed-clock support, while 'pll_base' is for
pll clock.  These two particular type of clocks are supposed to be
gracefully supported by the common clk api when it gets ready.
