PCI: Change pdev->rom_attr_enabled to single bit
Make 'rom_attr_enabled' a single bit in a bitfield and move it close to an
existing bitfield so that they can be merged.
This field is only used in 'drivers/pci/pci-sysfs.c' to store 0 or 1.
On x86_64, this shrinks the size of 'struct pci_dev' by 8 bytes from 3560
to 3552.
