Bump hekate to v5.3.3 and Nyx to v0.9.4

TODO:
This driver is a stub and relies on incorrect I2C requests.
The I2C driver needs to be updated with proper multi-xfer support.

For now it replies its whole register range, according to request size.
That's because the IC does not support the classic single transfer request-response style.
