[PATCH] Input: applespi: Fix build error without CONFIG_PCI

[YueHaibing]

If CONFIG_KEYBOARD_APPLESPI is set to y, but
CONFIG_PCI is not set, building will fails:

drivers/spi/spi-pxa2xx-pci.c: In function pxa2xx_spi_pci_probe:
drivers/spi/spi-pxa2xx-pci.c:208:8: error: implicit declaration of function pcim_enable_device;
 did you mean pci_enable_device? [-Werror=implicit-function-declaration]
  ret = pcim_enable_device(dev);
        ^~~~~~~~~~~~~~~~~~
        pci_enable_device
drivers/spi/spi-pxa2xx-pci.c:239:8: error: implicit declaration of function pci_alloc_irq_vectors;
 did you mean pci_alloc_consistent? [-Werror=implicit-function-declaration]
  ret = pci_alloc_irq_vectors(dev, 1, 1, PCI_IRQ_ALL_TYPES);
        ^~~~~~~~~~~~~~~~~~~~~

Make CONFIG_KEYBOARD_APPLESPI depends on CONFIG_PCI
to fix this.
