msm: pcie: remove IO/MEM resource in PCIe root complex driver 



PCIe root complex driver ioremaps IO and MEM resource but
does nothing with them. When MEM space is very large (ex: 1GB),
PCIe root bus driver fails to ioremap it. Therefore, remove
the ioremap of IO and MEM in PCIe root complex driver.
