Jim Mussared 119c88ef17 stm32/flash: Implement WB55 flash locking.
This is needed to moderate concurrent access to the internal flash, as
while an erase/write is in progress execution will stall on the wireless
core due to the bus being locked.

This implements Figure 10 from AN5289 Rev 3.

Jim Mussared 893f75546c stm32/boards/NUCLEO_WB55/rfcore_firmware.py: Increase GET_STATE timeout.
When installing WS firmware, the very first GET_STATE can take several
seconds to respond (especially with the larger binaries like
BLE_stack_full).

Allows stm.rfcore_sys_hci to take an optional timeout, defaulting to
SYS_ACK_TIMEOUT_MS (which is 250ms).

Jim Mussared 7c76a2dfcf stm32/rfcore: Add Python API for basic rfcore operations.
The new functions provide FUS/WS status, version and SYS HCI commands:
- stm.rfcore_status()
- stm.rfcore_fw_version(fw_id)
- stm.rfcore_sys_hci(ogf, ocf, cmd)

Damien George 4b5dd012e0 stm32/rfcore: Leave txpower level as default when initialising rfcore.
And provide a convenient API function to change it (currently unused).

Fixes issue #5985.

Damien George e965363b6b stm32: Refactor Bluetooth HCI RX to be independent of transport layer.
Now all HCI specific code (eg UART vs WB55 internal messaging) is confined
to modbluetooth_hci.c.

Damien George 69661f3343 all: Reformat C and Python source code with tools/codeformat.py.
This is run with uncrustify 0.70.1, and black 19.10b0.

Damien George 6a64b280d0 stm32: Add support for RF coprocessor on WB55 MCUs.
This requires a BLE wireless stack firmware to be already programmed in the
secure flash area of the device.
