ata: sata_fsl: fix cmdhdr_tbl_entry and prde struct definitions

The fields of the cmdhdr_tbl_entry structure all store __le32 values,
and so are the dba and ddc_and_ext fields of the prde structure. Define
these fields using the __le32 type to avoid sparse warnings about
incorrect type in assignment.

The debug message in sata_fsl_setup_cmd_hdr_entry() is changed to
display the correct values of the cmdhdr_tbl_entry fields on big endian
systems.
