bus: mhi: host: Switch trace_mhi_gen_tre fields to native endian

Each of the __field() macros were triggering sparse warnings similar to:
trace.h:87:1: sparse: sparse: cast to restricted __le64
trace.h:87:1: sparse: sparse: restricted __le64 degrades to integer
trace.h:87:1: sparse: sparse: restricted __le64 degrades to integer

Change each little endian type to its similarly sized native integer.
Convert inputs into native endian.
