While dpaa2_fd.simple structure fields are marked __leXX,
corresponding cpu_to_leXX / leXX_to_cpu conversions are missing.
While here, fix dpaa2_fd_{get,set}_bpid such that BMT, IVP bits
sharing the 16-bit field with BPID are not affected.
Fixes: d3269bdc7ebc ("bus: fsl-mc: dpio: add frame descriptor and
scatter/gather APIs")
