Checkpatch warns:
WARNING: Use 'if (IS_ENABLED(CONFIG...))' instead of '#if or #ifdef' where
possible
#31: FILE: board/ti/am64x/evm.c:31:
+#if IS_ENABLED(CONFIG_EFI_HAVE_CAPSULE_SUPPORT)
How about we drop the #if here and instead see possible solution below.

set the environment variable only if relevant config is enabled.
