We had that in mind while designing but we chose it this way. There are
not many fields to fill here, so it looks fine without macro's too.
I didn't wanted to create an abstraction layer here.

If i understand correctly you want me to rename misc_regs.h as clock.h?
Actually misc_regs.h have all miscellaneous registers for spear, like:
clock specific, reset register, some muxing registers too.. They are
not only for "clock". So we kept this name.
