Bradley Grove 8e65e2f07c [SCSI] esas2r: Fixes for big-endian platforms 
In esas2r_format_init_msg(), sgl_page_size and epoch_time params
are converted to little endian and the firmware version read from
the hba is converted to cpu endianess.

In esas2r_rq_init_request, correct and simplify the construction
of the SCSI handle.

These fixes are the result of testing on a PPC64 machine.

Bradley Grove 9588d24e36 [SCSI] esas2r: Directly call kernel functions for atomic bit operations 
Previously the code embedded the kernel's test_bit/clear_bit
functions in wrappers that accepted u32 parameters.  The
wrapper cast these parameters to longs before passing them
to the kernel's bit functions.   This did not work properly
on platforms with 64-bit longs.
