Both __PHYSICAL_START and LOAD_PHYSICAL_ADDR are defined to get aligned CONFIG_PHYSICAL_START, so we can replace __PHYSICAL_START with LOAD_PHYSICAL_ADDR. And then remove the definition of __PHYSICAL_START, which is only used to define __START_KERNEL.
Since <asm/boot.h> includes <asm/pgtable_types.h>, which includes <asm/page_types.h>, it is fine to move definition from <asm/boot.h> to <asm/page_types.h>.
