Commit 08177ece596c ("serial: asc: Adopt readl_/writel_relaxed()) is upsetting the build bots primarily because m68k allmodconfig builds have regressed. This is due to the unconditional use of readl_relaxed() which, although documented, does not currently exist for m68k.
This is trivially fixable for st-asc because we can just update the asc_in() accessor to make this conditional.

Notes: Will Deacon is working on a patchset to introduce readl_relaxed (and writel_relaxed) to all platforms. I intend to keep an eye on this work and will remove the conditional code in asc_in/out() when this is possible.
