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.

2cebfaab73 m1n1.hw.i2c: Reset status before transaction 
Reset the status register before each transaction. This is necessary if
we are taking over the peripheral after the Linux driver (e.g. in paused
hypervisor).

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
