[v2,0/7] accel/qaic: Initial AIC200 support

Message

Initial support to the driver to boot up AIC200. AIC200 uses BHIe
without BHI, which is something that the MHI bus has not supported until
now. While the MHI changes are listed first to facilitate cross-tree
merging, they are not needed until the last change in the series.

Also, AIC200 is a different product from AIC100 with MSI-X, different
BARs, and different MHI configuration so we finally need some
infrastructure in the driver to be able to handle product differences.
This is expected to evolve more over time.

v2:
-Remove inline on mhi_fw_load_error_dump() and shorten stack variable
lines
-Simplify kcalloc from mhi_alloc_bhi_buffer()
-Inline mhi_firmware_copy_bhi() and drop the function
-Fix spelling of MHI/BHIe in commit text of patch 2
-Drop MHI_FW_LOAD_UNKNOWN
-Simplify mhi_fw_load_type_get()
-Rename mhi_send_image_bhi() to mhi_load_image_bhi()
-Rename mhi_send_image_bhie() to mhi_load_image_bhie()
-Adjust the order of mhi_cntrl init in qaic_mhi_register_controller()
