Implement support for the USB488 defined READ_STATUS_BYTE and SRQ
notifications with ioctl, fasync and poll/select in order to be able
to synchronize with variable duration instrument operations.
Add ioctls for other USB488 requests: REN_CONTROL, GOTO_LOCAL and

So basically we are trying to use as many microframes as possible with as few
packets
per microframe as possible.
Did I understand this correctly?
Yes, you are right.
How will devices react if they expect to get 16 packets every 16th microframe,
but they get one packet every microframe inste

This change allows to get a driver instance of usb controller, which
registers an irq, now the interrupt names are unique:

Existing register access functions cp210x_get_config and cp210x_set_config
are cumbersome to use. This change introduces new functions specifically
for 16-bit registers that read and write simple u16 values.
