ARM: shmobile: bockw: define FPGA address and rename iomem variable
Bock-W board will needs more board specific ioremap() method. This patch tidyup current FPGA specific settings Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
