Add PHYSICAL_START kernel configuration parameter to set the address at which the kernel should be loaded. It has been observed on an sh7757lcr that simply modifying MEMORY_START does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such systems.
