[PATCH] x86: remove __phys_reloc_hide

[Namhyung Kim <namhyung@gmail.com>]

remove unnecessary use of RELOC_HIDE(). It only does simple addition of ptr
and offset, and in this case, offset 0, does nothing. It does NOT do anything
with linker relocation things. I could find no reason to use it.

The only user of __phys_reloc_hide() was __pa_symbol() so it can be removed
safely here.
