this commit is a combination of the following changes, which
significantly refactors usb core and class drivers.
1. unify usb buffers of each class driver to reduce iram usage
currently, many class drivers allocate their own buffer to receive
control out data, which is a waste of iram.
share one common buffer for that usage to address the issue.
2. simplify control request handling by implicitly receiving write
request data packets
change 1 above fixed the data destination. therefore, having the core
receive the data allows us to reduce the class driver's work and
simplifies the api.
3. enhance usb core's control request handling and unify the legacy
driver api
in order to implement change 2, both the legacy and new driver apis
should be supported. so that, using the designware driver as a
reference, the new driver api functionality is move into usb core.
this simplifies the usb device drivers by requiring them to implement
only the functionalities equivalent to the legacy api.
tested with ipodvideo(arc) and erosqnative(designware)

add needs_cpu_boost field to usb_class_driver and manage boost state in
usb_core, similar to needs_exclusive_storage.

this is required to make hid endpoint of iap class driver work,
especially on ipodvideo(arc).
at least for arc, it is required to set mps as 64 instead of 512 on
highspeed, or some accessories ignore incoming hid reports.

this invokes specified class driver's notify_event method.
initial purpose is to trigger a callback from isr, like a timer event.

- existing class drivers are placed to config 1
- drivers_connected==true is replaced with usb_config!=0
- supports config transition between nonzero configs
- STALL if request set_config was invalid

this commit has following changes:
- introduce `usb_drv_ep_spec` table to udc drivers, which represents
endpoint characteristics.
- introduce 'ep_allocs' table to class drivers, which represents what
endpoint type does the class driver want.
- implement endpoint matching logic to usb core.
this is a required step to implement usb config switching, because we
need to create config descriptors without actually initializing endpoints.

To enable, see setting under General Settings --> System --> USB-DAC.
On devices with few endpoints, this may not work while HID and/or
mass storage is enabled.
Adds new dedicated mixer channel.
setting usb-dac can have values:
- never (0)
- always (1)
- while_charge_only (2)
- while_mass_storage (3)

USB Driver-wise, it should be noted that this patch requires some
slight changes:
- proper blocking on control OUT transfers, to make sure the data is
received *before* using it, the usb_core should probably use that too
- drivers can now support interface alternate settings
- drivers can be notified of completion by a new fast handler, which
is called directly from the driver; this is is necessary for
isochronous transfers because going through the usb queue is way too
slow
Designware changes:
- enable for USBOTG_DESIGNWARE
- set maxpacketsize to 1023 for ISO endpoints

This needs support for usb interrupt transfers, so there are some changes in various USB drivers as well (only usb-drv-arc supports it at this point, others won't have working HID yet).
HID is disabled for now, as the apps/ part is not included yet.
