drm/amd/display: Create new i2c resource
[Why]
I2C code did not match dc resource model and was generally
unpleasant
[How]
Move code into new svelte dce_i2c files, replacing various i2c
objects with two structs: dce_i2c_sw and dce_i2c_hw. Fully split
sw and hw code paths. Remove all redundant declarations. Use
address lists to distinguish between versions. Change dce80 code
to newer register access macros.
