[PATCH] ARM: lpc18xx: define low-level debug symbol for LPC18xx/43xx

[Joachim Eastwood]

Using a dedicated symbol for low-level debugging instead of the
arch symbol will make this platform play nice when enabled on a
kernel that supports multiple platforms.

Hi Arnd,

As disscussed on the mailing list:
http://marc.info/?l=linux-arm-kernel&m=143202771500659&w=2

Patch should apply nicely on top of next/soc.
