Subject[PATCH 1/2] Introduce MSP_HAS_PCI config option.
Date
From: Anoop P A <anoop.pa@gmail.com>

Various chips in MSP family shares PCI block. Following patch introduce MSP_HAS_PCI config option
so that we can avoid adding seperate entries in arch/mips/pci/Makefile. Also getrid off SoC specific
flags from ops-pmcmsp.c
