Subject: [PATCH] asm-generic: correct reference to GENERIC_LIB_DEVMEM_IS_ALLOWED

Commit 527701eda5f1 ("lib: Add a generic version of devmem_is_allowed()")
introduces the config symbol GENERIC_LIB_DEVMEM_IS_ALLOWED, but then
falsely refers to CONFIG_GENERIC_DEVMEM_IS_ALLOWED (note the missing LIB
in the reference) in ./include/asm-generic/io.h.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

GENERIC_DEVMEM_IS_ALLOWED
Referencing files: include/asm-generic/io.h

Correct the name of the config to the intended one.

Fixes: 527701eda5f1 ("lib: Add a generic version of devmem_is_allowed()")
