brcm63xx: remove non runtime detect and refresh affinity patches

Remove the non runtime detect code since its effectiveness is dubious
and almost never used.
Also update affinity patches to work on top of it.

+Subject: [PATCH 31/53] MIPS: BCM63XX: replace irq dispatch code with a generic
+ version
+
+The generic version uses a variable length of u32 registers of u32/u64.
+This allows easier support for longer registers without having to rewrite
+verything.
+
+This "generic" version is not slower than the old version in the best case
+(= i == next set bit), and twice as fast in the worst case in 64 bits.
