The driver didn't stop the bounce buffer in case a data transfer
failed. This would lead to memory leakage if the communication
between the CPU and the card is unreliable. Add the missing call
to stop the bounce buffer.

Currently the serial code assumes that there is always at least one serial
port (and panics / crashes due to null pointer dereferences when there is
none).

This makes it impossible to use u-boot on boards where there is no (debug)
serial port, because e.g. all uart pins are muxed to another function.

This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which
defaults to y (preserving existing behavior), which can be set to n on
such boards to make them work.

This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing
running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial,
and is not necessary at this moment.

Do not add a bogus (pointing to a non existing serial port) stdout-path
alias to dts on boards without a serial port.

Note that we still define CONS_INDEX as this is used by the SPL where we do
not use DM_SERIAL and thus CONFIG_REQUIRE_SERIAL_CONSOLE is not honored.

We are getting away with this because the sun5i die actually has
an uart0, which in the A13 package is not routed to the outside,
so we are simply sending SPL bootup messages to the tx pin at the
edge of the die, and they go no further from there...

And sofar we only have one A13 board which does not have a serial
port, all others do have a serial port. This kinda makes sense since
the A13 is a much lower pincount package compared to all the other
sunxi SoCs.

USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.

Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.

This patch removes the powering off calls, fixing the undesirable power
bouncing.

Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now
