bte.c:
  After working with the chip designer some more, we have determined one
  more hardware register we were supposed to write to ensure the SHUB
  chip was ready for future transfers.  This patch fixes that.  This also
  allowed us to eliminate a udelay which was working around the problem.

  During retesting, we uncovered a race condition where transfer status
  was changed by a different cpu after we were expecting one value which
  cascaded to additional problems.  This patch uses a local variable to
  also eliminate that race.

con_font_set() sanitized.  We are passing console_font and flags into
the method in separate arguments and we are not messing with
console_font_op->data anymore - it's a userland pointer (to be annotated
several patches later in the series, due to another abuse of console_font_op
that needs to be fixed first), while console_font->data is kernel one
and they don't mix anymore.

We also do a sanity check (font width > 0) in the caller instead of
method instances, since we are already checking for width <= 32 and
height <= 32 there; doesn't make sense leaving that one in method
instances.

->con_font_copy() sanitized.  We extract the number of console to copy the
font from in the caller (it's taken from the field of console_font_op that
is normally used for font height - messy even for an ioctl, but that animal
used to be passed all the way down into console drivers).

With decoding done in con_font_copy(), we simply pass source console number
into the method.

Preparations for cleanups: con_font_op() is turned into a switch calling
con_font_{get,set,default,copy} depending on the operation required;
method ->con_font_op() also split, with NULL resulting in -ENOSYS on
operation in question.

Code that used to be in con_font_op() got slightly cleaned up after move
into new helpers (we are beginning to untangle the mess; there will be
more cleanups in the next patches).

Methods are currently using exact same arguments as old ->con_font_op().
That will change in subsequent patches, method by method (right now there's
a hell of a scary field reuse between them, making impossible to do any
static checks and practically begging for bugs).
