    powerpc/44x: Fix PCI MSI support for Maui APM821xx SoC and Bluestone
board

    This patch consists of:
    - Enable PCI MSI as default for Bluestone board
    - Change definition of number of MSI interrupts as it depends on SoC
    - Fix returning ENODEV as finding MSI node
    - Fix MSI physical high and low address
    - Keep MSI data logically

Which I can confirm:

this works:
git checkout 47da421981571c69ef29740cc55fa7248682e167
save this version of arch/powerpc/sysdev/ppc4xx_msi.c

this reboots:
git checkout 247540b03bfcbbe26b86692c9424195d76eb67f0

fix .config
CONFIG_PPC_DISABLE_WERROR=y
#CONDIF_PPC_WERROR is not used

cp ../ppc4xx_msi.c from 47da421981571c69ef29740cc55fa7248682e167 to
arch/powerpc/sysdev/ppc4xx_msi.c and voila this works.
