[PATCH for-6.2 0/2] target/sparc: Drop use of gen_io_end() |

The sparc frontend is now the only user of the obsolete gen_io_end()
function (used for icount support). This patchset removes the
use from sparc as well, and then tidies up the generic icount
infrastructure to remove the function altogether.
This is for-6.2 material because it's just cleanup.
There is a slight difficulty here with testing this: icount
doesn't seem to work for sparc Linux guests in master at the
moment. For instance if you get the advent calendar image from
https://www.qemu-advent-calendar.org/2018/download/day11.tar.xz
it will boot without icount with a command line like
qemu-system-sparc -display none -vga none -machine SS-20 -serial stdio
-kernel /tmp/day11/zImage.elf
But if you add '-icount auto' it will get as far as
"bootconsole [earlyprom0] disabled" and then apparently hang.
I'm not sure what's going on here :-(
(I filed this as https://gitlab.com/qemu-project/qemu/-/issues/499)
Anyway, these patches don't make the situation any worse...
