checkpatch: add IDR to the deprecated list

Browse Source 
As of commit 85656ec193, the IDR interface is marked as deprecated in
the documentation, but no checks are made in that regard for new code. 
Add the existing IDR initialization APIs to the deprecated list in
checkpatch, so that if new code is introduced using these APIs, a warning
is emitted.
