powerpc/fsl_pci: Fix pci stack build bug with FRAME_WARN

Fix this:

  CC      arch/powerpc/sysdev/fsl_pci.o
arch/powerpc/sysdev/fsl_pci.c: In function 'fsl_pcie_check_link':
arch/powerpc/sysdev/fsl_pci.c:91:1: error: the frame size of 1360 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

when configuring FRAME_WARN, by refactoring indirect_read_config()
to take hose and bus number instead of the 1344-byte struct pci_bus.
