[MIPS] merge GT64111 PCI routines and GT64120 PCI_0 routines

This patch has merged GT64111 PCI routines and GT64120 PCI_0 routines. GT64111 PCI is almost the same as GT64120's PCI_0. This patch don't change GT64120 PCI routines. Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
