We are about to create a standalone ACPI quirk module for the bcmstb controller. Lets move the register definitions into a separate file so they can be shared between the APCI quirk and the normal host bridge driver.

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.
