d135246a7d SAM3/4: Remove 'stalled' flag in UDP driver.

c7ef82c546 SAM3/4: Add delay between setting and clearing the endpoint RESET bit in sam_ep_resume(). 
We need to add a delay between setting and clearing the endpoint reset
bit in SAM_UDP_RSTEP. Without the delay the USB controller will (may?)
not reset the endpoint.

If the endpoint is not being reset, the Data Toggle (DTGLE) bit will
not to be cleared which will cause the next transaction to fail if
DTGLE is 1. If that happens the host will time-out and reset the bus.

Adding this delay may also fix the USBMSC_STALL_RACEWAR in
usbmsc_scsi.c, however this has not been verified yet.

bf096873a1 SAMV7 USBDEVHS: A problem occurred if the USB cable is unplugged while a large amount of data is send over an IN endpoint using DMA. If the USB cable is plugged in again after a few seconds it is not possible to send data over this IN endpoint again, all other endpoints work as expected. 
The problem occurs because if the USB cable is unplugged while an DMA transfer is in flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL is left in an undefined state.  The problem was fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a known state. Additionally all pending interrupts are cleared.

    up_registerdump: CPSR: 200b0253

It seems to be caused by the corrupted or wrong CPSR restored on return
from exception. NuttX restores the context using code like this:

    msr spsr, r1

GCC translates this to:

    msr spsr_fc, r1

As a result, not all SPSR fields are updated on exception return. This
should be:

    msr spsr_fsxc, r1

On some evaluation boards, spsr_svc may have totally invalid value at
power-on-reset. As it is not initialized at boot, the code above may
result in the corruption of cpsr and thus unexpected behavior.
