usb: uvc: use v4l2_fill_fmtdesc instead of open coded format name

2023-01-31T08:40:43Z

Since v4l2_fill_fmtdesc will be called in the ioctl v4l_enum_fmt anyway. We can set the format description and compressed flag from v4l_fill_fmtdesc and can remove the extra name field in uvc_format_desc.

usb: uvc: make uvc_format_desc table const

2023-01-31T08:40:42Z

Since the uvc_fmts array can not be modified we declare it const and change every user of the uvc_format_by_guid function aswell.

usb: uvc: move uvc_fmts and uvc_format_by_guid to own compile unit

2023-01-31T08:40:42Z

The media driver USB_VIDEO_CLASS and USB_F_UVC are using the same function uvc_format_by_guid. Since the function is inline, every user will get a copy of the used uvc_fmts array and the function. This patch moves the code to an own compile unit and add this dependency as UVC_COMMON to both users.
