[PATCH] PCI: rockchip: Enable the phy driver when controller is enabled

[Punit Agrawal]

The PCI controller on rk3399 requires the phy to correctly initialise
the PCIE phy. Without phy initialisation the host and end-point
controllers cannot be used.

To prevent building an unusable PCIe driver on rk3399, enable the phy
driver when the host or end-point driver is enabled.

Hi,

I've been caught out many times when booting off of PCI and finding
that the kernel cannot find rootfs due to the missing phy driver. The
patch should prevents this by fixing the Kconfig dependency
enablement. 

Thanks,
Punit
