cmd_sf: include header file common.h before div64.h

The header file div64.h includes <asm/types.h> which defines
the phys_addr_t according to the macro CONFIG_PHYS_64BIT, while
the macro CONFIG_PHYS_64BIT is included in common.h which comes
after div64.h, so in order to get consistent type definition for
phys_addr_t, common.h should be included before div64.h, Or else,
the parameters of phys_addr_t type will be passed wrongly when
CONFIG_PHYS_64BIT is defined.
