To support BHIe transfer directly from PBL, a policy needs to be added. With this policy, BHIe will be used to transfer firmware in PBL if the mhi controller has bhie regs, sets seg_len, and does not set fbc_download. The intention is to transfer firmware using BHIe in PBL without further BHIe transfers in SBL.

Create config structs for each card, and let the driver configure the qaic_device struct based on the configurations passed to the driver.
