6ddd89d0c9 [media] em28xx: create a common function for isoc and bulk URB allocation and setup
Rename the existing function for isoc transfers em28xx_init_isoc
to em28xx_init_usb_xfer and extend it.
URB allocation and setup is now done depending on the USB
transfer type, which is selected with a new function parameter.

afb177e065 [media] em28xx: rename function em28xx_uninit_isoc to em28xx_uninit_usb_xfer
This function will be used to uninitialize USB bulk transfers, too.
Also rename the local variable isoc_bufs to usb_bufs.

74209dc06a [media] em28xx: rename struct em28xx_usb_isoc_ctl to em28xx_usb_ctl
Also rename the corresponding field isoc_ctl in struct em28xx
to usb_ctl.
We will use this struct for USB bulk transfers, too.

515688a898 [media] em28xx: rename isoc packet number constants and parameters
Rename EM28XX_NUM_PACKETS to EM28XX_NUM_ISOC_PACKETS and
EM28XX_DVB_MAX_PACKETS to EM28XX_DVB_NUM_ISOC_PACKETS to
clarify that these values are used only for isoc usb transfers.
Also use the term num_packets instead of max_packets, as this
is how these values are used and called in struct urb.

890401364d [media] em28xx: Better support for the Terratec Cinergy HTC USB XS
This intializes the card just like the windows driver does

- the "HTC USB XS HD" uses the same firmware as the "HTC Stick HD";
- both have different GPIO and reg init sequences;

Tested only with DVB-C.
