irqchip/gic-v3-its: Remove artificial dependency on PCI
The GICv3 ITS doesn't really depend on PCI. Only the PCI/MSI part of it does, and there is no reason not to blow away most of the irqchip stack because PCI is not selected (though not selecting PCI seem to be asking for punishment, but hey...). So let's split the PCI-specific part from the ITS in the Kconfig file, and let's make that part depend on PCI. Architecture specific hacks (arch/arm{,64}/Kconfig) will be addressed in a separate patch. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
