Commit edff605421 introduces an empty invalidate_icache() function in
page.h for x86 but mistakenly places it outside the !__ASSEMBLY__
block. This causes build failure on x86.

Address this by moving the function definition to within the existing
!__ASSEMBLY__ block.

Fixes: edff605421 ("Avoid excess icache flushes in populate_physmap() before domain has been created")

Hi Stefano, Jan,

This commit fixes the build breakage in staging for me. I'm not sure
whether staging gets rebased so sending this as a separate commit.

Please feel free to fold it in if that makes sense.

Once again apologies for the breakage.

No, we don't re-base. If anything (e.g. when a fix doesn't
arrive pretty quickly or needs more thought) we revert.
