drivers/i2c/tas5825m: Add driver for TI TAS5825M amplifier
This adds a driver for the TI TAS5825M, documentation can be found here: https://www.ti.com/product/TAS5825M
This driver expects the mainboard using it to define tas5825m_setup, which uses the tas5825m_* functions to set configuration data. Each mainboard may have very different configuration data, depending on its audio hardware.
Tested on system76/addw2 and system76/oryp6, which will be added in a future patch.

Would be nice to add at least one of these mainboards first, then add the driver and select it where applicable. Otherwise, this code hasn't been build-tested.
