i8k: Tell gcc that *regs gets clobbered
commit 6b4e81db2552bad04100e7d5ddeed7e848f53b48 upstream.
More recent GCC caused the i8k driver to stop working, on Slackware
compiler was upgraded from gcc-4.4.4 to gcc-4.5.1 after which it didn't
work anymore, meaning the driver didn't load or gave total nonsensical
output.
As it turned out the asm(..) statement forgot to mention it modifies the
*regs variable.
Credits to Andi Kleen and Andreas Schwab for providing the fix.
