    PCI: use weak functions for MSI arch-specific functions · 4287d824
    Thomas Petazzoni authored
    Until now, the MSI architecture-specific functions could be overloaded
    using a fairly complex set of #define and compile-time
    conditionals. In order to prepare for the introduction of the msi_chip
    infrastructure, it is desirable to switch all those functions to use
    the 'weak' mechanism. This commit converts all the architectures that
    were overidding those MSI functions to use the new strategy.
    
    Note that we keep two separate, non-weak, functions
    default_teardown_msi_irqs() and default_restore_msi_irqs() for the
    default behavior of the arch_teardown_msi_irqs() and
    arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI
    code.
