USB: sl811-hcd: Fix device disconnect
A while ago I provided a patch that fixed device detection after device removal (USB: sl811-hcd: Fix device disconnect). Chris Brissette pointed out that the detection/removal counter method to distinguish insert or remove my fail under certain conditions. Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device has been inserted or removed.
