ARM: OMAP2xxx: hwmod: Add DMA support for SHAM module

The current OMAP2 SHAM support doesn't enable DMA
so add that support so it can use DMA just like OMAP3.

crypto: omap-sham - Add code to use dmaengine API

Add code to use the new dmaengine API alongside
the existing DMA code that uses the private
OMAP DMA API.  The API to use is chosen by
defining or undefining 'OMAP_SHAM_DMA_PRIVATE'.

This is a transitional change and the code that uses
the private DMA API will be removed in an upcoming
commit.

crypto: omap-sham - Add OMAP4/AM33XX SHAM Support

Add support for the OMAP4 version of the SHAM module
that is present on OMAP4 and AM33xx SoCs.

The modules have several differences including register
offsets, hardware XORing, and how DMA is triggered.
To handle these differences, a platform_data structure
is defined and contains routine pointers, register offsets,
bit shifts within registers, and flags to indicate whether
the hardware supports XORing and provides SHA1 results in
big or little endian.  OMAP2/OMAP3-specific routines are
suffixed with '_omap2' and OMAP4/AM33xx routines are suffixed
with '_omap4'.

Note: The code being integrated is from the TI AM33xx SDK
and was written by Greg Turner <gkmturner@gmail.com> and
Herman Schuurman (current email unknown) while at TI.
