This patch fixes an oops triggered at rmmod of isp116x-hcd
after the probe() has failed.
Also, it extends the error message printed, if the driver
cannot detect "Chip's Clock Ready" after a software reset.
As Ian Campbell recently reported, this happens if the
chip's H_WAKEUP pin is not pulled low during software reset.
Several people have already had this issue, hence the update
to the error message.
Also, extend the error message about the failed clock
detection after the software reset.

This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.
The driver:
- is relatively small, meant for use on embedded platforms.
- runs usbtests 1-14 without problems for days.
- has been in use by 6-7 different people on ARM and PPC platforms,
running a range of devices including USB hubs.
- supports suspend/resume of both the platform device and the root hub;
supports remote wakeup of the root hub (but NOT the platform device)
by USB devices.
- does NOT support ISO transfers (nobody has asked for them).
- is PIO-only.
