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 Change-Id: I8742fefa4bf02e728e34d5d8cbc0fda771e78ffb
