Encapsulate hardware interfaces in drivers

[sfe-SparkFro]

The current driver implementation requires different classes/files for each combination of chip and interface, which may become unmanageable as hardware support grows. Would be better if the interfaces were encapsulated by the driver for each chip with a common interface.

Then, instead of things like:

camera = HM01B0_PIO(
    i2c,
    pins = ...,
    sm_id = ...,
    resolution,
    ...
)

Can do something like:

camera_interface = camera_rp2_dvp_pio(
    i2c,
    pins = ...,
    sm_id = ...,
)

camera = HM01B0(
    camera_interface,
    resolution,
    ...
)
