[RFC: 2.6.21 patch] let PCI_MSI depend on EXPERIMENTAL

[Adrian Bunk]

We had during the last months have quite a few MSI bugs and even 
regressions due to:
- core kernel bugs,
- device driver bugs and
- hardware bugs

OTOH, MSI doesn't bring any real advantages for most users.

Let's therefore mark PCI_MSI as EXPERIMENTAL.
