[PATCH v2 0/2] soc: renesas: mfis: add hwspinlock support

To support hwspinlocks of an MFIS core, we first need to update the
driver to use raw_spinlocks. Patch 1 does this. Patch 2 then adds the
support for hwspinlocks.

Patches are based on linux-next as of 20260714, no more dependencies.
A branch for testing is here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/mfis/hwspinlock

It has been tested on a SparrowHawk board (R-Car V4H) with one MFIS
instance and an Ironhide board (R-Car X5H) with two MFIS instances.

Changes since v1:

* add patch 1 to use raw_spinlocks (Sashiko)
