drm/bridge: add support for TI TDP158

TDP158 is an AC-coupled DVI / HDMI to TMDS level shifting Redriver.
It supports DVI 1.0, HDMI 1.4b and 2.0b.
It supports 4 TMDS channels, HPD, and a DDC interface.
It supports dual power supply rails (1.1V on VDD, 3.3V on VCC)
for power reduction. Several methods of power management are
implemented to reduce overall power consumption.
It supports fixed receiver EQ gain using I2C or pin strap to
compensate for different lengths input cable or board traces.

Features

- AC-coupled TMDS or DisplayPort dual-mode physical layer input
to HDMI 2.0b TMDS physical layer output supporting up to 6Gbps
data rate, compatible with HDMI 2.0b electrical parameters
- DisplayPort dual-mode standard version 1.1
- Programmable fixed receiver equalizer up to 15.5dB
- Global or independent high speed lane control, pre-emphasis
and transmit swing, and slew rate control
- I2C or pin strap programmable
- Configurable as a DisplayPort redriver through I2C
- Full lane swap on main lanes
- Low power consumption (200 mW at 6Gbps, 8 mW in shutdown)

https://www.ti.com/lit/ds/symlink/tdp158.pdf

On our board, I2C_EN is pulled high.
Thus, this code defines a module_i2c_driver.

The default settings work fine for our use-case.
So this basic driver doesn't need to tweak any I2C registers.
