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.
