Data written/read from the command/response/data
buffers is done so in transaction sizes of 4 or 8
bytes. The data in those transactions will be
little endian byte order. The byte order of those
transactions must be corrected to represent the
data structures stored in the buffers correctly
for extraction of field data. The fields themselves
will be big endian byte ordering.
This patch also adds two attributes:
ATTR_MSS_OCMB_EXP_STRUCT_MMIO_ENDIAN_CTRL -
Controls whether or not bytes read from and
written two the buffer are swapped. The default
is to swap the byte order.
ATTR_MSS_OCMB_EXP_STRUCT_ENDIAN -
Controls whether or not the bytes of buffer
structure fields are little endian or not.
The default is big endian.

There are some helper function to force LE and I found a case
where I wanted to force BE so I added here also.

This commit adds a new exp_i2c_scom.H file which contains two
functions, i2c_get_scom and i2c_put_scom. These functions will
take in a fapi2 OCMB target, an address and a buffer that either
contains scom data to write or space for scom data to be written
to. The functions use the fapi2::puti2c / fapi2::geti2c interfaces
to perform the scoms.
