fw/qmod: enable modem RESET by default at bootlaforge/tool
When the uC firmware starts, assert the (high-active) _RESET GPIOs,
which will cause the transistors to drive the mPCIe slot !PERST
low.
There is of course a short instance of time between the uC reset
until it executes wwan_perst_init(). To avoid this, a hardware
pull-up would have to be re-worked onto the _RESET[1..4] signals
on the PCBA
