Writing the MHI SOC_RESET register is a device internal soft reset: it
only asks the modem to restart itself, so it is useless once the device
has stopped servicing MHI.
Every MHI implementation I've looked at has the SOC_RESET register implemented as a direct hardware signal to the PMIC to reset the SOC. No firmware involvement.
