sh: sh7785lcr: fix PCI address map for 32-bit mode

Browse Source 
Fix the problem that cannot work PCI device on 32-bit mode because
influence of the commit 68b42d1b54
("sh: sh7785lcr: Map whole PCI address space."). So this patch was
implement like a 29-bit mode, map whole physical address space of
DDR-SDRAM.
