Subject: [PATCH 5.15 001/277] lib/logic_iomem: correct fallback config references

From: Johannes Berg <johannes.berg@...el.com>

[ Upstream commit 2a6852cb8ff0c8c1363cac648d68489343813212 ]

Due to some renaming, we ended up with the "indirect iomem"
naming in Kconfig, following INDIRECT_PIO. However, clearly
I missed following through on that in the ifdefs, but so far
INDIRECT_IOMEM_FALLBACK isn't used by any architecture.
