usb/hcd-ehci-sysbus: Convert to QOM realize

The SysBus qdev initfn merely calls SysBusDeviceClass::init, so we can
replace it with a realizefn already. This avoids getting into any initfn
ambiguity with the upcoming Faraday EHCI implementation.

Rename internal usb_ehci_initfn() to usb_ehci_realize() to allow to...

usb/hcd-ehci: Split off instance_init from realize

This makes the mem MemoryRegion available to derived instance_inits.

Keep the bus in realize for now since naming breaks in instance_init.

dma: eliminate DMAContext

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

usb/ehci: Clean up SysBus and PCI EHCI split

SysBus EHCI was introduced in a hurry before 1.3 Soft Freeze.
To use QOM casts in place of DO_UPCAST() / FROM_SYSBUS(), we need an
identifying type. Introduce generic abstract base types for PCI and
SysBus EHCI to allow multiple types to access the shared fields....

ehci: Verify a queue's ep direction does not change

ehci_fill_queue assumes that there is a one on one relationship between an ep
and a qh, this patch adds a check to ensure this.

Note I don't expect this to ever trigger, this is just something I noticed...

ehci: Lower timer freq when the periodic schedule is idle

Lower the timer freq if no iso schedule packets complete for 64 frames in
a row.

We can safely do this, without adding latency, because:
1) If there is isoc traffic this will never trigger
2) For async handled interrupt packets (only usb-host), the completion handler...
