Apollo Lake SOC tie VCCIOA to VNN for LPDDR4

[IShen]

We followed Intel CRB 572383 to connect SOC VCCIOA with VNN power on our LPDDR4 platform

, but another Intel CRB (561529) said VCCIOA should be connected

to VDDQ for LPDDR4 memory , we would like to know if it will impact boot up ,

Our platform is hang on post code 2E when power on ( memory initial ).
