[PATCH 0/4] irqchip/alpine-msi: Cleanups and debug logging

[Eliav Farber]

This series contains a few small cleanups for the Alpine MSIX irqchip
driver, followed by the addition of some optional debug logging.

Patches 1-3 are trivial, no-functional-change cleanups that address
the coding-style issues checkpatch reports for the file: convert the
license boilerplate to an SPDX identifier, drop the redundant
<asm/msi.h> include (already pulled in via <linux/msi.h>), and fix the
missing space after a comma in a GENMASK_ULL() invocation.

Patch 4 adds an info message on successful initialisation and debug
messages on the MSI interrupt allocation and free paths, to make it
easier to follow the driver flow when debugging.

Build-tested for arm64 with the aarch64 toolchain and KCFLAGS=-Werror.
The driver is used by the Alpine V2, Alpine V3 and AL8 SoCs.
