a7663b862e zephyr: Replace deprecated time conversion macro.
The SYS_CLOCK_HW_CYCLES_TO_NS macro was deprecated in zephyr commit
8892406c1de21bd5de5877f39099e3663a5f3af1.  This commit updates MicroPython
to use the new k_cyc_to_ns_floor64 api and fix build warnings in the zephyr
port.

This change is compatible with Zephyr v2.1 and later.

2befcb8a9d zephyr/i2c: Add support for hardware i2c.
Adds support for hardware i2c to the zephyr port. Similar to other ports
such as stm32 and nrf, we only implement the i2c protocol functions
(readfrom and writeto) and defer memory operations (readfrom_mem,
readfrom_mem_into, and writeto_mem) to the software i2c implementation.
This may need to change in the future because zephyr is considering
deprecating its i2c_transfer function in favor of i2c_write_read; in this
case we would probably want to implement the memory operations directly
using i2c_write_read.

Tested with the accelerometer on frdm_k64f and bbc_microbit boards.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
