media: staging/ipu7: add CONFIG_PCI dependency

From: Arnd Bergmann <[email protected]>

This driver fails to build when PCI is disabled:

drivers/staging/media/ipu7/ipu7.c: In function 'ipu7_pci_config_setup':
drivers/staging/media/ipu7/ipu7.c:2260:15: error: implicit declaration of function 'pci_enable_msi'; did you mean 'pci_enable_sriov'? [-Wimplicit-function-declaration] drivers/staging/media/ipu7/ipu7.c:2775:1: error: data definition has no type or storage class [-Werror]
driver(ipu7_pci_driver);
drivers/staging/media/ipu7/ipu7.c:2764:26: error: 'ipu7_pci_driver' defined but not used [-Werror=unused-variable]

Add the required Kconfig dependency.
