[#5972] Sl811-hcd.c USB removal
Chris Brissette pointed out that the Detection / Removal counter method
to distinguish instert or remove my fail under certain conditions.
Latest SL811HS datasheet (Document 38-08008 Rev. *D) adds following to
bit 6 of the Interrupt Status Register.
... Otherwise, this bit is used to indicate the presence of a device,
?\226?\128?\1531?\226?\128?\153 = device ?\226?\128?\152Not present?\226?\128?\153
and ?\226?\128?\1530?\226?\128?\153 = device ?\226?\128?\152Present.?\226?\128?\153 In this mode, check this bit along with bit
5 to determine whether a device has been inserted or removed.
