[OpenBIOS] [PATCH 1/2] pci: fix compilation for architectures where OFMEM isn't available

[Mark Cave-Ayland]

Commit 0d3345f9 "pci: add ob_pci_unmap() to unmap PCI memory" accidentally
broke compilation for architectures where OFMEM is unavailable such as x86.

Add the appropriate #if defined(CONFIG_OFMEM)...#endif block to ob_pci_unmap()
so that compilation can at least succeed for these architectures.
