[RFC][PATCH 20/34] x86/cpu: Remove superfluous cache alignment assignments

[Dave Hansen]

From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx>

Now that the boot CPU's ->x86_cache_alignment is authoritative
and is is consistently established, these other copies only
serve to clobber it needlessly.  Remove them.
