While I don't see ARCH_TIMER_MEM_MAX_FRAMES changing, this would be
nicer to ensure the result obviously matches.

As for wording, I'd perfer:

pr_err(FW_BUG "too many frames, only %u are permitted.\n",
ARCH_TIMER_MEM_MAX_FRAMES);

... so as to avoid any confusion between spec versions and so on. We can
reconsider the message if/when that changes.

Thanks,
Mark.
