device/pci_rom: Add simple pci_rom_free()
It adds simple function, which frees the memory which
could be allocated by pci_rom_probe(). In the next step
it will be modified to free only memory, which was mapped
from CBFS.
BUG=b:278264488
TEST=Build and run with additional debug prints added
to confirm that data are correctly unmapped
