bcm53xx: add clk tree driver

These patches are written by Broadcom and will be in mainline Linux
kernel soon. I had some problems to get them backported to kernel 4.1,
so currently they are only available for 4.3.

+Subject: [PATCH 44/50] clk: cygnus: Convert all macros to all caps
+
+The macros that are being used to initialize the values of the clk
+structures should be all caps.  Find and replace all of them with their
+relevant counterparts.
