clang doesn't like the array here:

ec-utils-0.0.1-r3361: In file included from usb_updater.c:32:
ec-utils-0.0.1-r3361: In file included from ../../include/usb_descriptor.h:14:
ec-utils-0.0.1-r3361: ../../chip/g/usb_hw.h:29:14: error: tentative array definition assumed to have
ec-utils-0.0.1-r3361: one element [-Werror]
ec-utils-0.0.1-r3361: static int (*usb_iface_request[]) (struct usb_setup_packet *req);
ec-utils-0.0.1-r3361: ^
ec-utils-0.0.1-r3361: 1 error generated.
But it's willing to forgive if this is extern. It should be extern
anyway.

The control endpoint (EP0) can receive some Setup packets that
are specific to individual Interfaces. The USB_DECLARE_IFACE
macro is used to register the callbacks that an interface
implementation provides to handle those Setup packets.
This change cleans up the callback API a bit, so that we don't
have to export the internal workings of the Cr50's EP0 interrupt
handler.
BUG=chrome-os-partner:34893
BRANCH=none
TEST=make buildall, manual
Connect the Cr50 to my workstation via USB:
* /bin/dmesg reports no errors
* verify EP0 with lsusb -v -d 18d1:5014
* verify EP1 with './extra/usb_console -e 1 -p 5014' (reverses
case of input text)
* verify EP2 with the 'hid' command on the EC console (types a 'g')

Our USB buffers are just arrays of uint8_t in program RAM, so
let's treat them that way. The DMA descriptors are in normal RAM,
too.

This moves the STM32-specific code out of the common header file
and into the chip directory where it belongs. Note that this
doesn't actually change the code for non-STM32 SoCs; that will
happen in a separate CL for clarity.
