[PATCH v2] kconfig: remove references to docs/misc/kconfig{,-language}.txt files

[Dmytro Prokopchuk1 <dmytro_prokopchuk1@xxxxxxxx>]

These files 'docs/misc/kconfig{,-language}.txt' were deleted, but
references are still present in Xen. Remove them to clean-up.

Fixes: 044503f61c95 ("docs: Delete kconfig docs to fix licensing violation")
Fixes: f80fe2b34f08 ("xen: Update Kconfig to Linux v5.4")
