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.
