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 Change-Id: Ibc9aad34b6bf101a3a0c06b92ed2dc6f2d7b9b33 Signed-off-by: Grzegorz Bernacki <bernacki@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/74778 Reviewed-by: Karthik Ramasubramanian <kramasub@google.com> Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de> Reviewed-by: Himanshu Sahdev <himanshu.sahdev@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
