Subject: [PATCH] Fix AT91 UDC driver on boards without vbus.
While porting Barebox to one of our boards, we found that the AT91 UDC driver
will fail to connect to USB hosts, and will spam the console with errors if
the VBUS pin isn't connected.

The current implementation fakes a memory-mapped I/O device
at 0x3f8 and 0x2f8, then uses platform read/write functions
to do the actual reading and writing. These platform functions
only exist for the x86 platform; better to move the I/O

using request_ioport_region.

Linux specifies the linux,stdout-path property in the /chosen node
in the devicetree. Unfortunately this is ignored in most cases.
For cases in which barebox uses this property for its own use we
translate this into a Linux boot arg with:
- the console name provided by the serial driver
- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.
So with this it's for devicetee enabled boards no longer necessary
to manually assign a console= parameter. Should a user not want
to use the automatically assigned parameter it should do:
global.linux.bootargs.console=

ubiformat needs the subpagesize to work correctly. The kernel uses
sysfs to pass the subpagesize, but in barebox we have the possibility
to extend struct mtd_info_user. Add a corresponding field and use it
in ubiformat.

mtd->read returns the number of bitflips as positive numbers.
Instead of returning these numbers Return -EUCLEAN when the bitflip
threshold has been reached, 0 otherwise.
