powerpc: Merge serial.h

[David Gibson]

This patch merges the ppc32 and (trivial) ppc64 versions of serial.h.
Mostly this is just an #ifdef merge, with the 32/64 ifdef being folded
in with the existing ifdefs for various embedded platforms from the
32-bit version.  Notable changes:
	- We fold ppc32's pc_serial.h into serial.h, because there's
no clear reason for keeping it separate.
	- We abolish the SERIAL_DEV_OFFSET macro; no-one was using it.

Built for 32bit multiplatform (ARCH=powerpc), built and booted on
POWER5 LPAR (ARCH=powerpc), built for Walnut (ARCH=ppc).
