Early firmware for the Scarlett Gen 4 devices has sufficient
differences that it is better to enforce a minimum firmware version
than to try and work around those differences. Add a minimum firmware
version field to the device info struct, and display a message if the
firmware version is too old. Only create the Firmware Version and MSD
(optional) controls in this case.

Gen 2/3 interfaces would only use 0/1 values for input level and
phantom power switch controls. Gen 4 interfaces use the second bit to
indicate that the state should be changed (or is changing), and the

Writing Scarlett Gen 4 parameters differs from Gen 2 and Gen 3:
- the values are written into a shared write location
- the values are only byte-sized
- the read locations now extend beyond 0xFF
- a separate NVRAM save step is no longer required
This patch implements that alternate write style, triggered by setting
the config item size field to zero.
The write address is specified through a new config set field
gen4_write_addr.

gen3b into gen3b/c (for 4i4/8i6 vs 18i8/18i20), we can use

- struct scarlett2_usb_volume_state,
- #define SCARLETT2_USB_VOLUME_STATUS_OFFSET, and
