Make sure we're using the new macro, so our
resume signaling will always pass certification.

As per the SAF1761 data sheet[0], the DcChipID register represents
the hardware version number (0001h) and the chip ID (1582h) for the
Peripheral Controller.

However as per the ISP1761 data sheet[1], the DcChipID register
represents the hardware version number (0015h) and the chip ID (8210h)
for the Peripheral Controller.

This patch adds support for both the chip ID values.

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

The isp1760 driver registration function returns an error if USB is
disabled. This made sense when the driver only supported host
controllers, but now that it supports peripheral controllers host
support isn't mandatory anymore.

Fix this by returning an error only when both the HCD and UDC functions
are disabled, either through the kernel configuration or at runtime.

Both isp1760_register() and isp1761_pci_probe() check whether USB is
disabled by calling usb_disabled(), and bail out with an error if it is.
One check is enough, remove the PCI-specific check.

Enable compilation of the isp1760 driver in pure host mode, pure device
mode, or dual-role mode.

Now that this is DRD, it doesn't make sense to keep it under
drivers/usb/host.
