[SCSI] ipr: add endian swap enablement for 64 bit adapters
A change in the hardware design of the chip for the new adapters changes the
default endianness of MMIO operations. This patch adds a register definition
which when written to with a predefined value will change the endianness
back to what the driver expects.
This patch also fixes two problems found during testing.
First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only
reserved one byte. The correct amount to reserve is 2 bytes.
Second, the reserved field of the ipr_hostrcb64_error structure only reserved
2 bytes. The correct amount to reserve is 16 bytes.
