The user mode libsahara library relied on header file
drivers/mxc/security/sahara2/include/sahara.h. However, to make
the lib build after headers_install step and to remove dependency on
kernel source, moved this header to include/linux/mxc_sahara.h.
These are the necessary changes in the SAHARA driver to use the new
header file in the new location.

To allow SCC2 and SAHARA drivers to work as loadable modules, needed
to add GPL license to SAHARA driver, export a couple of functions
from SCC2 driver, and the following data buffer mapping change in
SAHARA driver:
When compiled as a loadable module, a data buffer to be DMA'ed in the
SAHARA driver may not be in the kernel direct-mapped region but in
the "Kernel module space" between TASK_SIZE and high_memory-1
(see http://www.arm.linux.org.uk/developer/memory.txt). In this
scenario, the driver canno simply use the __pa macro to obtain
the physical address. It must walk the page tables to find the
page and use the page_to_phys function to find the physical
address that corresponds to the data buffer.

This replaces IO_ADDRESS with ioremap in drivers. Drivers needing more
than trivial changes are not included.

The spba defaults to all masters enabled and this is fine as
all chips only have ARM and SDMA as masters.
