[top_earlgrey, fpv] Connectivity test currently broken

[vogelpi]

Description

The connectivity test (triggered using util/dvsim/dvsim.py hw/top_earlgrey/formal/chip_conn_cfg.hjson) is currently broken on master, earlgrey_1.0.0 and earlgrey_1.0.0._presilicon. The root cause is the following commit 1194ca4 which enabled the pull-up setting for the power-on reset signal. The change itself is not controversial at all and was requested by the PD team but the FPV flow / connectivity test needs to be aligned accordingly.

I don't have sufficient expertise to take care of this on my own. I might be able with some help from an expert like @matutem and I am happy to collaborate.

If in the meantime someone wants to run the connectivity test, the mentioned commit above needs to be reverted to make things pass again.
