1a77571557 chickens: Disable SMC traps from EL1 to EL2 
This behavior isn't really compliant with the architecture, so turn it
off.

f2eac15ca7 tools/chainload.py: Default to copying SEPFW 
This doesn't really take any significant time and is the correct thing
to do. Use --no-sepfw for e.g. serial bring-up where doing the ADT dance
costs measurable time.

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
