Rework the tegra slave controller init to look more like in
tegra-i2c.c. This makes the nvec init reliable. Also add de-init of
the slave to be used during suspend.

This patch alters a line of code to make it more readable
and easier to understand. The purpose of the original line
of code was to compute the amount of memory to request from
kmalloc. This mulit-step algorithm was being done in one
line of code, thus making it more difficult to understand.
Therefore, I split this algorithm into three logical steps.

This patch fixes two issues within bcm/Bcmchar.c. The
first condition in the or statement checks if variable
IoBuffer.OutputLength, defined from user space, is
greater than the maximum value allowed for an
unsigned short. IoBuffer.OutputLength is then used
in a kmalloc call to return a pointer to memory. If
this size is greater than an unsigned short, it
becomes useless. The second condition in the or statement
checks if the same variable, IoBuffer.OutputLength is
equal to zero before invoking the kmalloc call. In
this case, if a zero size is sent to kmalloc, a valid
pointer to memory is returned instead of the expected NULL.

Add support for GTT based scrolling. Instead of pushing bits around we simply
use the GTT to change the mappings. This provides us with a very fast way to
scroll the display providing we have enough memory to allocate on 4K line
boundaries. In practice this seems to be the case except for very big displays
such as HDMI. It works out nicely on the usual configurations are netbooks and
tablets.
