sh: Provide a 29/32-bit physical hint for bootloaders.
Shoves a magic word in to the empty_zero_page section for the
bootloader to work out whether to start the kernel in 29-bit
or 32-bit mode.
[ Renesas CPUs already take care of the initial PMB mappings entirely
in hardware and decide on 29-bit/32-bit physical depending on which
pin powered up the CPU, so this is mostly for ST parts. -- PFM ].
