This patch set adds usb device support for SAM9x60 SoC.
The DPRAM memory for the USB High Speed Device Port (UDPHS) hardware
block was increased and the allocation method is changed. This patch
series simplifies the endpoint allocation scheme to acomodate this SoC
and the old ones.

Changes in v3:
- rebase on top of testing/next
- depends on https://lore.kernel.org/linux-arm-kernel/cover.1594231056.git.mirq-linux@rere.qmqm.pl/
- extend usba_udc_config structure with endpoint preallocaion flag
- collect acked-by tags

Changes in v2:
- drop the patch that adds reference to pmc for sam9x60
- use dt-bindings: usb prefix
- enable usb device in device tree
