This commit should deal with
fixing the way USB_MCTLR_REG
is zeroed in order to disable
the USB controller along with
its tranceiver.

This commit should deal with updating
the way USBD was handling the DMA
engine. Based on the #73803 request
DMA should be handled via the DMA
driver API class and not directly.

When device was resumed from sleep OUT endpoints were most
likely not enabled due to condition that checked pending transfer.
Configured OUT endpoints should be enabled (ready for RX)
if they were enabled by interfaces.
Now separate bit field enabled is added and check to
see if OUT endpoint should be ready for reception after
sleep is done.

Callback with USB_DC_EP_DATA_OUT was called directly from
interrupt handler (handle_ep0_rx()) while rest of the interrupt
conditions were not checked yet.
Some interfaces started next transfer directly from this callback
resulting in case where TX endpoint was still marked as busy
and transfer was eventually abandoned.
Now message is sent from all affected endpoints after every USB
pending interrupt is handled.

Switching from write to read on EP0 is done when data is
transmitted.
Additionally receiver is enabled when NAK is created in
response to OUT token. This may happen when host sent
ZLP before everything was transmitted.
This case flushed receiver FIFO which could lead to
setup packet corruption.

Add support for automatic control of PLL for USB subsystem.
This utilized virtual USB clock present in clock control.
USB driver enables PLL when device is attached or USB
sends resume signaling.
PLL can be turned off (if application does not requested it)
when device is detached (application request)
or USB host sends suspend request.
When VBUS is not present or application did not started USB yet
PD_DOMAIN_SYS is also not acquired that allows for deep
sleep. When USB is active deep sleep will never be activated.

When EP0 was disabled EP0 was setup to ignore setup and
out packets.
In usb_dc_ep_enable() function mask was never cleared.
It resulted in USB stop functioning after application
disabled endpoint (usb_disable()) and then tried
to enable usb again.
