You moved more than just register definitions into pcie-brcmstb.h you 
also moved internal structure definitions, enumerations, etc. which are 
not required since pcie-brcmstb-acpi.c does not access the brcm_pcie 
structure but open codes accesses to the MISC_STATUS register instead.

There are no include guards added to this file (it is debatable whether 
we should add them), and it is also not covered by the existing BROADCOM 
BCM2711/BCM2835 ARM ARCHITECTURE MAINTAINERS file entry.

Given that there can be new platforms supported by this PCIe controller 
in the future possibly with the same limitations as the 2711, but with a 
seemingly different MISC_STATUS layout, you will have to think about a 
solution that scales, maybe we cross that bridge when we get there.
