idr test suite: remove usage of the deprecated ida_simple_xx() API

Browse Source 
Patch series "ida: Remove the ida_simple_xxx() API", v3.

These are the final steps in removing the ida_simple_xxx() API.

This series was last proposed in August 2024.  Since then, some users of
the old API have be re-introduced and then removed.

A first time in drivers/misc/rpmb-core.c, added in commit 1e9046e3a1
("rpmb: add Replay Protected Memory Block (RPMB) subsystem") (2024-08-26)
and removed in commit dfc881abca ("rpmb: Remove usage of the deprecated
ida_simple_xx() API") (2024-10-13).

A second time in drivers/gpio/gpio-mpsse.c, added in commit c46a74ff05
("gpio: add support for FTDI's MPSSE as GPIO") (2024-10-14) and removed in
commit f57c084928 (gpio: mpsse: Remove usage of the deprecated
ida_simple_xx() API) (2024-11-22).

Since then, I've not spotted any new usage.

So things being stable now, it's time to end this story once and for all.


This patch (of 3):

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

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range()/ida_alloc_max() is inclusive.  But because of the ranges
used for the tests, there is no need to adjust them.

While at it remove some useless {}.
