The goal with this patch is actually to free acpi_lpss.c from
delivering the clock for this driver.

The LPSS PWM does not get it's clock from the LPSS 100Mhz source
clock, which means we have to have the rate of it's clock hard-coded.
Since it's already hard coded also in this driver for PCI mode in any
case, it makes no sense to also have it there.

So this patch will allow us to cleanup acpi_lpss.c. We can now remove
the confusing "shared clock" structure where the hard coded rates are
held. This device is the only one that would need it.


Thanks,
