[PATCH RESEND] pps: Remove usage of the deprecated ida_simple_xx() API

[Christophe JAILLET]

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.

This patch has been sent about 3 months ago [1].
A gentle reminder has been sent 1 month later [2].

Neither one got any reply.

So, I'm adding Andrew Morton in To:, in order to help in the merge process.

Context:
=======
All patches to remove the ida_simple API have been sent.
Matthew Wilcox seems happy with the on going work. (see [3])

Based on next-20240412
$git grep ida_simple_get | wc -l
