* force_eeprom_read=0 disables HAT I2C
  Although setting force_eeprom_read=0 has always prevented the HAT EEPROM
  from being read, with the recent changes to support Power HAT+s it does
  not prevent an early scan to see if such an EEPROM exists. This can be
  problematic for applications where the I2C0 pins have been repurposed.
  Change the inhibit logic to cut all HAT I2C probing off at the knees,
  including any automatic settings of usb_max_current_enable, as it should
  always have done.
