HMC_MODE must be set to a value that routes a host controller port to USB
pin group 1 (see Table 73). OTG_SYSCON_1.USB1_TRX_MODE must be
set to 1 to allow proper bidirectional operation of the 4-wire USB transceiver.
OTG_SYSCON_2.USBx_SYNCHRO must be set to allow proper bidirectional
signaling on
RTC_WAKE_INT/USB1.SE0.
