Pull request for UEFI sub-system for efi-2020-10-rc1

This series comprises error corrections for the UEFI subsystem:

* correct consideration of timestamps for variable authentication
* correct collection of data regions for code authentication
* correct unit tests to test loading dbx
* enable FAT_WRITE as required by the UEFI spec

The boot manager uses log functions instead of printf() and debug().

The UEFI intialization state is exported.

- 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.

- Merge a fix to the gpio uclass and a test for it.

currently gpio hog function is not tested with "ut dm gpio"
so add some basic tests for gpio hog functionality.

For this enable GPIO_HOG in sandbox_defconfig, add
in DTS some gpio hog entries, and add testcase in
"ut dm gpio" command.
