[PATCH] [POWERPC] iSeries: we need vio_enable_interrupts

[Stephen Rothwell <sfr@canb.auug.org.au>]

Commit 3d0e91f7ace12499c4b00088e9a6b1361e1bb0ca introduced a requirement
for vio_enable_interrupts which iSeires has never needed.  So create a
dummy one.

Paul, this is a fix for a 2.6.23 regression.  I should do a better fix
for 2.6.24.  Built for iseries_defconfig, ppc64_defconfig and
allmodconfig.
