Add a PHY configuration sequence for the SM8550 which uses a Qualcomm
Gen 2 version 1.2 CSI-2 PHY.

The PHY can be configured as two phase or three phase in C-PHY or D-PHY
mode. This configuration supports two-phase D-PHY mode.

This should sparkle warnings.

There is no user of it. You must organize your patches in logical junks.
Adding piece of structure without users is not a logical chunk.

Hi Krzysztof,

Sure, will move this patch to "media: qcom: camss: Add sm8550 support",
It is used in below code.

+	case CAMSS_8550:
+		regs->lane_regs = &lane_regs_sm8550[0];
+		regs->lane_array_size = ARRAY_SIZE(lane_regs_sm8550);
+		regs->offset = 0x1000;
+		break;
 	default:

Thanks,
Depeng
