Alexander Gordeev	6b2fd7efeb	PCI/MSI/PPC: Remove arch_msi_check_device() ... Move MSI checks from arch_msi_check_device() to arch_setup_msi_irqs(). This makes the code more compact and allows removing arch_msi_check_device() from generic MSI code.

Alistair Popple	e2c37d9083	powerpc: Added PCI MSI support using the HSTA module ... The PPC476GTR SoC supports message signalled interrupts (MSI) by writing to special addresses within the High Speed Transfer Assist (HSTA) module. This patch adds support for PCI MSI with a new system device. The DMA window is also updated to allow access to the entire 42-bit address range to allow PCI devices write access to the HSTA module.
