Subject: [PATCH v3 2/4] phy: qcom: edp: Fix the DP_PHY_AUX_CFG registers
 count

On all platforms supported by this driver, there are 13 DP_PHY_AUX_CFGx
registers. This hasn't been an issue so far on currently supported
platforms, because the init sequence never spanned beyond DP_PHY_AUX_CFG9.

However, on the new upcoming Glymur platform, these are updated along
with the rest of the init sequence.

So update the size of the array holding the config to 13.
