Serial port is attached to XTFPGA boards as native endian device, now
that earlycon parameter parser understands mmio32native put it into
earlycon kernel parameter. This makes early console functional on both
little- and big-endian CPUs with identical kernel command lines.

I2C controller is attached to XTFPGA boards as native endian device, mark
it as such in DTS.
Set register width in DTS to 4, this way it works both for little- and
big-endian CPUs.

Ethernet controller is attached to XTFPGA boards as native endian device,
mark it as such in DTS and pass correct endianness in platform data.
This makes network functional on big-endian CPUs.

Pull xtensa updates from Chris Zankel:

 - fix remaining issues with noMMU cores
 - fix build for cores w/o cache or zero overhead loop options
 - fix boot of secondary cores in SMP configuration
 - add support for DMA to high memory pages
 - add dma_to_phys and phys_to_dma functions.

There are no .bootstrap or .ResetVector.text sections linked to the
vmlinux image, drop these sections from vmlinux.ld.S. Drop
RESET_VECTOR_VADDR definition only used for .ResetVector.text.

Drop remapped copies of primary and secondary reset vectors, as modern
gdb don't have problems stepping through instructions at arbitrary
locations. Drop corresponding sections from the corresponding linker
scripts.

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel
config, so for testing coverage it is convenient to build all of the dtbs.
This builds all dts files in the tree, not just targets listed.

Use the same offset from the default physical memory start address as in
LOAD_MEMORY_ADDRESS definition.
