platform/x86: mlx-platform: Add dependency on PCI to Kconfig

Add dependency on PCI to avoid 'mlx-platform' compilation error in case
CONFIG_PCI is not set.

Failed on i386:
CONFIG_ACPI=y
CONFIG_ISA=y

Error In function 'mlxplat_pci_fpga_device_init':
implicit declaration of function 'pci_request_region':
 6204 |         err = pci_request_region(pci_dev, 0, res_name);
      |               ^~~~~~~~~~~~~~~~~~
      |               pci_request_regions
