[PATCH] usb: s3c-hsotg: add isochronous transfers support

[Robert Baldyga]

Hello,

There is my initial proposal for isochronous transfers support in s3c-hsotg
driver.

This patch does few modifications:
- Fix few functions to make them usable in isochronous transfers handling.
- Add few fields to s3c_hsotg_ep structure, used for isochronous ep handling.
- Add isochronous specific endpoint descriptor fields handling.
- Add high-speed high-bandwidth trensfers support by correct Multi Count
  handling and Odd/Even frame toggle for interval=1.
- Improve endpoint interrupt handling by ignoring unneded interrupts for
  isochronous endpoints.

Best regards
