clk: bcm281xx: don't use unnamed structs or unions
The Broadcom Kona clock code, as originally written, made use of
unnamed union and struct fields. This is a feature present in C11,
and is a GNU extension otherwise. It worked very well for me.
Unfortunately, Russell King reported that this feature was not
supported in a build environment he used, which meant attempting
to build this code failed spectacularly.
Add names to these unnamed fields, and update the code accordingly.
