[PATCH] arm64: Kconfig: select ALPINE_MSI only if PCI is selected

[sudeep.holla@arm.com (Sudeep Holla)]

Even when PCI is disabled, ARCH_ALPINE selects ALPINE_MSI triggerring
the following config warning:

warning: (ARCH_ALPINE) selects ALPINE_MSI which has unmet direct dependencies (PCI)

This patch makes selection of ALPINE_MSI conditional on PCI.

Hi Arnd,

I happened to end up with a config without PCI when switching between
DT and ACPI and saw the config warnings. This is against today's next,
not sure if you have some fix already queued. Also I am not sure if
ALPINE_MSI is must for this platform to boot in which case it needs to
select PCI.

Regards,
Sudeep
