Hi,

This is cleaning up some of the remaining things to be able to apply
-Warray-bounds and -Wzero-length-bounds globally. Only after doing my
own version of the port_status patch did I find Arnd's earlier
patches, including for the weird Broadcom stuff[1].

No binary differences.

v2:
- use 0x80 as base for brcm registers (stern)
- switch HCS_N_PORTS_MAX to decimal (stern)
- update various comments (stern)
v1: https://lore.kernel.org/lkml/20210818043035.1308062-1-keescook@chromium.org

Thanks!

-Kees
