powerpc/pasemi: Search for PCI root bus by compatible property (250a9350) · Commits · 戴 / test

Pasemi arch code finds the root of the PCI-e bus by searching the device-tree for a node called 'pxp'. But the root bus has a compatible property of 'pasemi,rootbus' so search for that instead. Signed-off-by:
