rt2x00: make csr_cache and csr_addr an union

Browse Source 
The csr_cache and csr_addr pointers are both the same size
and they are never used both by the same driver. This makes
them a nice candidate for an union.
We could merge into 1 pointer, but that would either upset sparse,
or require a lot of __force casts.
