Recently the PLL input clock of Promise 2027x is sometimes detected

It seems sometimes the mdelay() function is not as precise as it
used to be. Per Alan's advice, HT or power management might affect
the precision of mdelay().
This patch calls gettimeofday() to mesure the time elapsed and
calculate the PLL input clock accordingly.

Maybe Bahadir could also help to verify if it helps to his "hda lost interrupt"
problem.
Hi,
As per the "hda lost interrupt" problem, I tried 2.6.22 and it didn't
make any difference. Then I tried 2.6.21 with pdc202xx_new.c file from
2.6.19 (the working one). I had to only retain
pdcnew_config_drive_xfer_rate() from 2.6.21 to make it compile, and I
still had the same result. I guess this means its a change outside the
driver that breaks it on my platform? I will git-bisect and see.
Thanks,
Bahadir
