[PATCH v3] checkpatch: remove %p4cn

[Aditya Garg]

%p4cn was recently removed and replaced by %p4chR in vsprintf. So,
remove the check for %p4cn from checkpatch.pl.

Fixes: 37eed892cc5f ("vsprintf: Use %p4chR instead of %p4cn for reading data in reversed host ordering")
Signed-off-by: Aditya Garg <gargaditya08 at live.com>

v2: Add specific check for %p4chR as suggested by Joe Perches.
v3: Remove blank lines from the tag block.
