qmod: Disable hub reset and EEPROM erase/write by default 

We recently introduced ALLOW_PEER_ERASE to control if the firmware
should contain code for the SAM3 to reset each other on QMOD.

Let's use the same define to also remove code for putting the USB
hub into reset as well as code for erasing + writing the hub EEPROM.

This is needed only during production, but it shouldn't be enabled
during normal operation of the product at the end user.
