Thomas Gleixner a6825f1c1f x86: hpet: workaround SB700 BIOS
AMD SB700 based systems with spread spectrum enabled use a SMM based
HPET emulation to provide proper frequency setting. The SMM code is
initialized with the first HPET register access and takes some time to
complete. During this time the config register reads 0xffffffff. We
check for max. 1000 loops whether the config register reads a non
0xffffffff value to make sure that HPET is up and running before we go
further. A counting loop is safe, as the HPET access takes thousands
of CPU cycles. On non SB700 based machines this check is only done
once and has no side effects.

Based on a quirk patch from: crane cai <crane.cai@amd.com>
