You won't need a special driver, I guess that the include file with the
LPC22XX port definitions from asm-arm/arch-lpc22xx/serial isn't used.
Try to modify asm-arm/serial.h so that it contains nothing more than
this:

#ifndef __ASM_SERIAL_H
#define __ASM_SERIAL_H
#include <asm/arch/serial.h>
#endif
