console: Add compile-time fast path when only CBMEM console is used
A common use case when running coreboot on production systems is that
only the CBMEM console (the one with the least impact on boot speed) is
enabled. In this case, some of the code in the console subsystem has no
effect. Due to the way it's all genericized over multiple consoles and
tied together with function pointers, not all of this can be
compile-time eliminated automatically, so this patch adds a little
helper to facilitate that. This results in roughly 200 (compressed)
bytes of savings per stage on an arm64 system.
