ahci: compile out msi/msix infrastructure
Quoting Arnd:
The AHCI driver is used for some on-chip devices that do not use PCI
for probing, and it can be built even when CONFIG_PCI is disabled, but
that now results in a build failure:
ata/libahci.c: In function 'ahci_host_activate_multi_irqs':
ata/libahci.c:2475:4: error: invalid use of undefined type 'struct msix_entry'
ata/libahci.c:2475:21: error: dereferencing pointer to incomplete type 'struct msix_entry'
Add ifdef CONFIG_PCI_MSI infrastructure to compile out the multi-msi and
multi-msix code.
