5e5b83e7a2 m1n1.hw.nco: Add NCO driver 
Apple SoCs have an NCO block used for generating audio master clocks.

The block performs fractional division of a higher-rate input clock and
contains a counter which is partially implemented as a LFSR. Credit
goes to Hector for reversing the divisor register semantics.

a40840f13c proxy: Expose usb_iodev_vuart_setup 
Expose the usb_iodev_vuart_setup function in uartproxy. This opens
the secondary ACM pipe to new uses outside the hypervisor. E.g. it can
be set up as another stream for sending proxy requests.

Sample usage from proxyclient:

    p.usb_iodev_vuart_setup(p.iodev_whoami())
    p.iodev_set_usage(IODEV.USB_VUART, USAGE.UARTPROXY)
    # the second virtual serial now also serves proxy

anything, but it does make this sysreg trap performance-critical,
so we have to move its handling into the C side.

1d932888f9 Add command categories to reduce command clutter 
Based on a suggestion from Ludwig Schubert it now uses the inspect class
to generate signatures of the functions for the help messages and
the qualified names which is a big improvement.

Also greatly reduced the clutter by putting the class functions into seperate
categories based on their class name. Now the top level help fits on one
page making it much more readable.

interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
