pata_hpt3x2n: fix clock turnaround
The clock turnaround code still doesn't work for several reasons: - 'USE_DPLL' flag in 'ap->host->private_data' is never initialized or updated, so the driver can only set the chip to the DPLL clock mode, not the PCI mode; - the driver doesn't serialize access to the channels depending on the current clock mode like the vendor drivers, so the clock turnaround is only executed "optionally", not always as it should be; - the wrong ports are written to when hpt3x2n_set_clock() is called for the secondary channel; - hpt3x2n_set_clock() can inadvertently enable the disabled channels when resetting the channel state machines.
