d135246a7d SAM3/4: Remove 'stalled' flag in UDP driver.
The flag is not necessary. The state of the endpoint can be determined
using 'epstate' instead.

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.

3f22b63321 SAM3/4: Fix GPIO pull-up/down code.
Enabling the pull-down resistor while the pull-up resistor is still enabled
is not possible. In this case, the write of PIO_PPDER for the relevant I/O
line is discarded. Likewise, enabling the pull-up resistor while the
pull-down resistor is still enabled is not possible. In this case, the
write of PIO_PUER for the relevant I/O line is discarded.

cf35bb0b18 SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is configured as input.
The value of a GPIO input is only sampled when the peripheral clock for
the port controller the GPIO resides in is enabled. Therefore we need
to enable the clock even when polling a GPIO.

f982180ec7 SAM3/4 Timer: Remove broken definitions for BMR register.
Per documentation SAM4S and SAM4E have the BMR register values
as they are already defined. No need for chip specific values.

In addition:
 - CONFIG_ARCH_CHIP_SAM4s has wrong lower case 's' so the definitions would
   not be used anyways for SAM4S builds.
 - TC_BMR_TC2XC2S_TIOA2 does not make sense. There is no way to loop back
   TC2's TIOA2 into itself.
