The idea is to have an unique place to decide the pin-port
per platform.
So let's create this function now without any functional
change. Just adding together code from hdmi and dp together.

We will soon need to make that pin port association per
platform, so let's try to simplify it beforehand.
Also we are moving the backwards port to pin

Our current logic to read LSPCON's current mode, stops retries and
breaks wait-loop, if it gets LSPCON_MODE_INVALID as return from the
core function. This doesn't allow us to try reading the mode again.
This patch removes this condition and allows retries reading
the currnt mode until timeout.
Th
It's an observation during some CI tests that few LSPCON chips
respond slow while system is under load, and need some delay
while reading current mode status using i2c-over-aux channel.
This patch:
- Adds few retries and delays before declaring a read
failure from LSPCON hardware.
- Changes the
