serial: timbuart: make sure last byte is sent when port is closed
Fix a problem in early versions of the FPGA IP.
In certain situations the IP reports that the FIFO is empty, but a byte is
still clocked out. If a flush is done at that point the currently clocked
byte is canceled.
This causes incompatibilities with the upper layers when a port is closed,
it waits until the FIFO is empty and then closes the port. During close
the FIFO is flushed -> the last byte is not sent properly.
Now the FIFO is only flushed if it is reported to be non-empty. Which
makes the currently clocked out byte to finish.

USB: EHCI: fix controller wakeup flag settings during suspend
This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers. When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.
In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops). This requires extra code, but the total delay
time is reduced.
There are also a few additional minor cleanups.

USB: EHCI: clear PHCD before resuming
This is a bug fix for PHCD (phy clock disable) low power feature:
After PHCD is set, any write to PORTSC register is illegal, so when
resume ports, clear PHCD bit first.
