firmware/rpc: added #[repr(C)] for structs.

firmware/i2c: rewrite I2C implementation
...
* Never drive SDL or SDA high. They are specified to be open
collector/drain and pulled up by resistive pullups. Driving
high fails miserably in a multi-master topology (e.g. with
a USB I2C interface). It would only ever be implemented to
speed up the bus actively but that's tricky and completely
unnecessary here.
* Make the handover states between the I2C protocol phases (start, stop,
restart, write, read) well defined. Add comments stressing those
pre/postconditions.
* Add checks for SDA arbitration failures and stuck SCL.
* Remove wrong, misleading or redundant comments.

runtime: Stop kernel CPU before restarting comms CPU on panic
...
Before, the system would enter a boot loop when a panic occurred
while the kernel CPU was active (and panic_reset == 1), as
kernel::start() for the startup kernel would panic.
