Michael Ellerman 329105ce53 powerpc/64s: Fix get_hugepd_cache_index() build failure
With CONFIG_BUG=n, the 64-bit Book3S build fails with:

  arch/powerpc/include/asm/book3s/64/pgtable-64k.h: In function 'get_hugepd_cache_index':
  arch/powerpc/include/asm/book3s/64/pgtable-64k.h:51:1: error: no return statement in function returning non-void

Currently the body of the function is just BUG(), so when CONFIG_BUG=n
it is an empty function, leading to the error.

get_hugepd_cache_index() should never be called, the only call is behind
an is_hugepd() check, which is always false for this configuration.

Instead mark it as always inline, and change the BUG() to BUILD_BUG().
That should allow the compiler to see that the function is never called,
and therefore that it never returns, fixing the build error.
