PCI/MSI: Move pci_disable_msi() to api.c
msi.c is a maze of randomly sorted functions which makes the code
unreadable. As a first step split the driver visible API and the internal
implementation which also allows proper API documentation via one file.
Create drivers/pci/msi/api.c to group all exported device-driver PCI/MSI
APIs in one C file.
Begin by moving pci_disable_msi() there and add kernel-doc for the function
as appropriate.
