[PATCH] ppc64 iSeries: iSeries_VpdInfo.c cleanups

Clean up iSeries_VpdInfo.c:
	- white space and comment fixes
	- make a function static
	- the functions here are only called from iSeries_pci.c, so
	  CONFIG_PCI will be set (so remove check)
	- only build when CONFIG_PCI is set
	- remove unneeded includes and cast
