None of the USB drivers currently support entering deep sleep mode
while USB is active. To protect USB from malfunctioning lock deep
sleep in USBPhyHw::init.
Perform isochronous endpoint processing from the frame interrupt
rather than the endpoint interrupt. Isochronous endpoints to not
generate interrupts normally and are intended to be handled from
the start of frame interrupt.
Implement the USB abort function so interrupts wont fire for a
transfer that has been aborted. The transfer may still take place
but the buffer passed into endpoint_write or endpoint_read will not
be used.
Move the USBPhy header files into usb/device/USBPhy. Also move hal
and target USB files since mbed 2 does not compile when these files
are present without the USBPhy headers.
