Fixing checkpatch.pl warnings.

Most warnings are "Missing a blank line after declarations". I'm also
adding blank lines between multi-line comments and statements.

Ran with --ignore BRACES,SPDX_LICENSE_TAG,VOLATILE,SPLIT_STRING,
AVOID_EXTERNS,USE_SPINLOCK_T,NEW_TYPEDEFS,INITIALISED_STATIC,
FILE_PATH_CHANGES to reduce noise. Now there is only one type of
warning, with two instances:

WARNING: Prefer using '"%s...", __func__' to using 'dmb', this function's name, in a string
+       __asm__ volatile("dmb sy");

WARNING: Prefer using '"%s...", __func__' to using 'dsb', this function's name, in a string
+       __asm__ volatile("dsb sy");
