Simon Xue f6a80248e3 phy: rockchip-inno-combphy: support low power consumption mode

Support low power consumption mode when PCIe suspend.

1. Add missing Kconfig and Makefile
2. Add usb3phy_grf_p reset
3. Turn off PCIe phy pd
4. Write some more MAGIC registers to enter low power mode like following:
	/* enter PCIe phy low power mode */
	writel(0x36, priv->mmio + 0x2150);
	writel(0x36, priv->mmio + 0x3150);
	writel(0x02, priv->mmio + 0x21e8);
	writel(0x02, priv->mmio + 0x31e8);
	writel(0x0c, priv->mmio + 0x2080);
	writel(0x0c, priv->mmio + 0x3080);
	writel(0x08, priv->mmio + 0x20c0);
	writel(0x08, priv->mmio + 0x30c0);
	writel(0x08, priv->mmio + 0x2058);

	writel(0x10, priv->mmio + 0x2044);
	writel(0x10, priv->mmio + 0x21a8);
	writel(0x10, priv->mmio + 0x31a8);
	writel(0x08, priv->mmio + 0x2058);
	writel(0x08, priv->mmio + 0x3058);
	writel(0x40, priv->mmio + 0x205c);
	writel(0x40, priv->mmio + 0x305c);
	writel(0x08, priv->mmio + 0x2184);
	writel(0x08, priv->mmio + 0x3184);
	writel(0x00, priv->mmio + 0x2150);
	writel(0x00, priv->mmio + 0x3150);
	writel(0x10, priv->mmio + 0x20e0);
	writel(0x00, priv->mmio + 0x21e8);
	writel(0x00, priv->mmio + 0x31e8);
