When obtaining the BHI or BHIe offsets during the power up preparation phase, range checks are missing. These can help controller drivers avoid accessing any address outside of the MMIO region. Ensure that mhi_cntrl->reg_len is set before MHI registration as it is a required field and range checks will fail without it.
