usb: dwc3: convert TRBs into bitshifts
this will get rid of a useless memcpy on IRQ handling, thus improving driver performance. Tested with OMAP5430 running g_mass_storage on SuperSpeed and HighSpeed. Note that we are removing the little endian access of the TRB and all accesses will be in System endianness, if there happens to be a system in BE, bit 12 of GSBUSCFG0 should be set so that HW does byte invariant BE accesses when fetching TRBs.
