[PATCH 9/9] ARM: BCM283x: Register fixed clocks for uart in the DT.

[Eric Anholt]

We were previously relying on the fixed clock registration in
clk-bcm2835, but there doesn't seem to be any real reason to not just
define it in the DT (and for the 2836 port, I would have needed to
change the clock's physical address in clk-bcm2835.c).  Also, because
we weren't registering the apb_pclk in clk-bcm2835 as a clock device,
we were picking up the uart clock node as apb_pclk by accident.

This gets serial working on 2836.
