[PATCH 2/2] PCI: Change the type of 'rom_attr_enabled' in 'struct pci_dev'

[Christophe JAILLET]

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.
This goes from 3560 to 3552.
