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 |
^

.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.
