patches: make ACPI gpio configuration depend on kernel >= 3.19

The GPIO configuration in the hci_bcm driver is now fetched from ACPI,
which only works in kernel version >= 3.19. In addition it used these
GPIO informations with the gpio consumer framework which was added in
3.13, deactivate these new features if the kernel does not support them.
