Subject: [PATCH] mediatek: Set default value for Panel Orientation connector prop.

From: Mark Yacoub <markyacoub@...gle.com>

[Why]
Creating the prop uses UNKNOWN as the initial value, which is not a
supported value if the props is to be supported.

[How]
Set the panel orientation default value to NORMAL right after creating
the prop.

Tested on Jacuzzi(MTK)
Fixes IGT@..._properties@..._properties-sanity-{atomic,non-atomic}
