x86/amd: Fix L1i and L2 cache sharing information for AMD family 15h processors
BugLink: http://bugs.launchpad.net/bugs/954576
commit 32c3233885eb10ac9cb9410f2f8cd64b8df2b2a1 upstream.
For L1 instruction cache and L2 cache the shared CPU information
is wrong. On current AMD family 15h CPUs those caches are shared
between both cores of a compute unit.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=42607
