V4L/DVB: uvcvideo: Add support for Packard Bell EasyNote MX52 integrated webcam

The camera requires the STREAM_NO_FID quirk. Add a corresponding entry
in the device IDs list.

V4L/DVB: uvcvideo: Use POLLOUT and POLLWRNORM for output devices

The V4L2 specification requires drivers to use the write events in the
file operations poll handler for output devices. The uvcvideo driver
erroneously used read events for all devices. Fix this.

The UVC relative controls (exposure time, iris, focus, zoom, pan/tilt)
are write-only (despite the UVC specification stating that the GET_CUR
request is mandatory). Mark the controls as such, and report the related
V4L2 controls V4L2_CTRL_FLAG_WRITE_ONLY.

uvcvideo: Power line frequency control doesn't support GET_MIN/MAX/RES

Issuing a GET_MIN request on the power line frequency control times out
on at least the Apple iSight. As the UVC specification doesn't list
GET_MIN/MAX/RES as supported on that control, remove them from the
uvc_ctrls array.

uvcvideo: Make button controls work properly

According to the v4l2 spec, writing any value to a button control should
result in the action belonging to the button control being triggered.
UVC cams however want to see a 1 written, this patch fixes this by
overriding whatever value user space passed in with -1 (0xffffffff) when
the control is a button control.

uvcvideo: Support menu controls in the control mapping API

The UVCIOC_CTRL_MAP ioctl doesn't support menu entries for menu
controls. As the uvc_xu_control_mapping structure has no reserved
fields, this can't be fixed while keeping ABI compatibility.

Modify the UVCIOC_CTRL_MAP ioctl to add menu entries support, and define
UVCIOC_CTRL_MAP_OLD that supports the old ABI without any ability to add
menu controls.
