PCI/MSI: irqchip: Fix PCI_MSI dependencies
The PCI_MSI symbol is used inconsistently throughout the tree, with some drivers using 'select' and others using 'depends on', or using conditional selects. This keeps causing problems; the latest one is a result of ARCH_ALPINE using a 'select' statement to enable its platform-specific MSI driver without enabling MSI: warning: (ARCH_ALPINE) selects ALPINE_MSI which has unmet direct dependencies (PCI && PCI_MSI) drivers/irqchip/irq-alpine-msi.c:104:15: error: variable 'alpine_msix_domain_info' has initializer but incomplete type static struct msi_domain_info alpine_msix_domain_info = { ^~~~~~~~~~~~~~~ drivers/irqchip/irq-alpine-msi.c:105:2: error: unknown field 'flags' specified in initializer .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^ drivers/irqchip/irq-alpine-msi.c:105:11: error: 'MSI_FLAG_USE_DEF_DOM_OPS' undeclared here (not in a function) .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^~~~~~~~~~~~~~~~~~~~~~~~ There is little reason to enable PCI support for a platform that uses MSI but then leave MSI disabled at compile time. Select PCI_MSI from irqchips that implement MSI, and make PCI host bridges that use MSI on ARM depend on PCI_MSI_IRQ_DOMAIN. For all three architectures that support PCI_MSI_IRQ_DOMAIN (ARM, ARM64, X86), enable it by default whenever MSI is enabled.
