mscan: too much data copied to CAN frame due to 16 bit accesses
Due to the 16 bit access to mscan registers there's too much data copied to
the zero initialized CAN frame when having an odd number of bytes to copy.
This patch ensures that only the requested bytes are copied by using an
8 bit access for the remaining byte.

The doorbell register was being unconditionally swapped. In x86, that
meant it was being swapped to BE and written to the descriptor and to
memory, depending on the case of blue frame support or writing to
doorbell register. On PPC, this meant it was being swapped to LE and
then swapped back to BE while writing to the register. But in the blue
frame case, it was being written as LE to the descriptor.
The fix is not to swap doorbell unconditionally, write it to the
register as BE and convert it to BE when writing it to the descriptor.

I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.
Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.
Finally, update the git URL since I'll take over running the main repo
for a while.
Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).
