rom loader: fix sparc -kernel boot.
Changes:
(1) register pstrcpy_targphys() in rom list, it is used for kernel
command lines by a number of architectures.
(2) add rom_ptr() function to get a pointer for applying changes
to loaded images. Needed for example to tell the linux kernel
where it finds the initrd image by updating the header.
(3) make sparc use rom_ptr for initrd setup.
booting sparc-test works now, and 'info roms' shows this:
(qemu) info roms

addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img"

reboot via 'system_reset' works too.
