The SHM bridge makes the Qualcomm RB3 and SM8150-HDK reset while probing
the RMTFS (in qcom_scm_assign_mem()). Blacklist the SHM Bridge on
corresponding platforms using SoC-level compat string. If later it's
found that the bad behaviour is limited just to the particular boards
rather than SoC, the compat strings can be adjusted.
