[PATCH 1/2] arm64: errata: Mark GIC-700 #2941627 N/A in silicon-errata

[TAKANO Mitsuhiro]

The GIC-700 #2941627 entry in the arm64 silicon-errata table names
ARM64_ERRATUM_2941627 in its Kconfig column, but no Kconfig file defines
that symbol and no code refers to it, so a reader who follows the name
finds nothing at the other end.

The workaround has no Kconfig option: irq-gic-v3.c passes the GICD_IIDR
value to gic_enable_quirks(), which matches it against gic_quirks[], and
gic_enable_quirk_arm64_2941627() enables a static branch.  The table
already records workarounds of that kind as "N/A", for example NVIDIA
T241-FABRIC-4, a GIC workaround like this one.

Set the Kconfig column to "N/A", as the table does for workarounds
that have no option.  The row stays because this file acts as the
registry of software workarounds in the kernel: deleting it would drop
the table's only pointer to gic_enable_quirk_arm64_2941627().

Only the text of the table changes, and no build was run.
