Linux Virtualization - Feb 2013 - [PATCH v2] arch/x86/xen: remove depends on CONFIG_EXPERIMENTAL

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in
Kconfigs.

 - drop EXPERIMENTAL from bool and help text too.

Please do not change the text this way.
The fact that CONFIG_EXPERIMENTAL is going away it doesn't change the
fact that this feature is experimental.
Maybe you want to replace EXPERIMENTAL with experimental, or if
experimental has become as taboo word, I am sure you can find a suitable
synonym.
