6d5f89c7b4 USB: EHCI: remove PORT_RWC_BITS when clearing USB_PORT_FEAT_ENABLE
In the ClearPortFeature/USB_PORT_FEAT_ENABLE case, ehci_hub_control()
would read from status_reg, clear PORT_PE, and write the result back to
status_reg. This would clear any bits in PORT_RWC_BITS that were set in
the registers. Fix this by masking these bits off before the write.

Since this masking is common across all ClearPortFeature cases, move it
into a single early location to avoid duplicating it.

Remove the same bugfix from ehci-tegra.c's tegra_ehci_hub_control(), now
that this case is correctly handled by the core.

cae18768ac USB: serial: ipaq: remove product and vendor module parameters
This driver is for devices that are no longer being made, so the ability
to add new device ids when loading the module is not a feature that
anyone uses anymore.  So remove it, which simplifies the startup code a
lot, and saves space.

If you still need to dynamically load device ids, that can be done
through sysfs.

6feff1b92b EHCI: don't try to clear the IAAD bit
This patch (as1541) corrects a small mistake in ehci-hcd.  The IAAD
(Interrupt on Async Advance Doorbell) bit in the USBCMD register is
designed, as its name says, to act as a "doorbell".  That is, the
driver activates the bit by setting it to 1, and the hardware
deactivates it later by setting it back to 0.  The driver cannot clear
the bit by writing a 0 to it; such writes are simply ignored.

Therefore there is no reason for ehci-hcd to try to clear the bit.
The patch removes the two instances where such attempts occur.
