Merge branch '2020-07-01-kconfig-etc-updates' into next

- Resync Kconfiglib with the v14.1.0 release.
- Re-sync our <linux/compiler*h> files with v5.7-rc5 from upstream.
- Fully resync checkpatch.pl with v5.7 release.

To safely to all of the above, we have a few bugfixes about functions
that need a 'static inline' but weren't.  We also stop setting
CROSS_COMPILE in arch/*/config.mk.  Finally, with the above changes
boards can now opt-in to optimizing inlining and we do this for the
socfpga stratix10 platform for space savings.
