[PATCH] ARM: LPC32XX: adding a LPC3XXX machine for backwards compatibility

[Ben Gardiner]

In the previous release of the lpc3250 kernel support -- a patch against
2.6.27.8 -- the machine type registered was LPC3XXX. This patch proposes
to enable a compatibiluty machine definition so that existing u-boots
can use a newer kernel without being re-flashed.
