[PATCH v2 1/8] powerpc/fsl_uli1575: Misc cleanup

[Pali Rohár]

From: Christophe Leroy <christophe.leroy at csgroup.eu>

Use a single line for uli_exclude_device().

Add uli_exclude_device() prototype in ppc-pci.h and guard it.

Remove that prototype from mpc85xx_ds.c and mpc86xx_hpcn.c files.

Make uli_pirq_to_irq[] static as it is used only in that file.
