Jim Mussared 61d1e4b01b extmod/nimble: Make stm32 and unix NimBLE ports use synchronous events.
This changes stm32 from using PENDSV to run NimBLE to use the MicroPython
scheduler instead.  This allows Python BLE callbacks to be invoked directly
(and therefore synchronously) rather than via the ringbuffer.

The NimBLE UART HCI and event processing now happens in a scheduled task
every 128ms.  When RX IRQ idle events arrive, it will also schedule this
task to improve latency.

There is a similar change for the unix port where the background thread now
queues the scheduled task.

Damien George 894c550c86 stm32: Refactor bluetooth stack/hci/driver bindings.
This makes a cleaner separation between the: driver, HCI UART and BT stack.
Also updated the naming to be more consistent (mp_bluetooth_hci_*).

Work done in collaboration with Jim Mussared aka @jimmo.

Damien George a5d97f1db9 stm32: Add soft timer implementation, using SysTick at 1ms resolution.
This commit adds an implementation of a "software timer" with a 1ms
resolution, using SysTick.  It allows unlimited number of concurrent
timers (limited only by memory needed for each timer entry).  They can be
one-shot or periodic, and associated with a Python callback.

There is a very small overhead added to the SysTick IRQ, which could be
further optimised in the future, eg by patching SysTick_Handler code
dynamically.

Damien George 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.
