Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:

a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.

The format:

1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
   distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
   underscores.

Merge errno.h, resource.h, rtc.h, sections.h, serial.h and sockios.h,
where i386 and x86_64 have no or only trivial comment/include guard
differences.

Build tested on both 32-bit and 64-bit, and booted on 64-bit.

[tglx: fixup Kbuild as well]
