use_dma parameter was designed to enable the dma on the chip. It was
enabled by default.

It comes from the time when the dma was not reliable. Now it has been
working ok in production.

This patch removes this parameter.

Parameter use_msi was used to enable msi irq on usb338x chips, it was
enabled by default.

There is no reason to prefer non-msi irq on usb338x, and it falls back
to non msi on error.

Therefore remove this option.

This patch removes the full_speed parameter used force full-speed
operation.

It was designed exclusively for testing purposes, and there is no
reason to maintain this in a production kernel.

use_dma_chaining module parameter was designed to avoid creating one irq
per package on a group of packages (with the help of the driver's flag
no_interrupt).

Unfortunately, when this parameter is enabled, the driver fails to work
on both net2280 and 3380 chips.

This patch removes this parameter, which was disabled by default.

If the caller of uvc_alloc() does not provide enough
