sparc,sparc64: unify Kconfig files

Merge all of sparc64 Kconfig to sparc Kconfig.
The merge was checked by:
- visual inspection in menuconfig
- result of allnoconfig, allmodconfig, allyesconfig was checked before and after
- result of a number of randconfig was checked before and after

scripts/diffconfig was used to check if the config differed before and after

The validity of the test was checked by on purpose introducing
a few bugs - and they were all caught by first run.
