The NRF5x driver transmits a byte by writing it to the uart data
register and then waiting for the TXRDY event indicating that this
byte was sent. If another UART interrupt comes in at the right time
the the UART ISR handler will process and clear the TXRDY event,
even though this interrupt is not enabled. This causes serial_putc
to get stuck waiting on an already cleared TXRDY.
This patch fixing the lockup by preventing the UART ISR from handling
the TXRDY event if this interrupt is not enabled.

This release brings the support of Keil RTX with uVisor on mbed OS, plus
several other improvements.
**New features**
* Integration in Keil RTX in mbed OS.
* Secure dynamic allocation APIs.
* Box initialization routines.
* Register gateway.
* vMPU recovery generalized for both Kinetis and ARMv7-M MPUs.
* APIs for per-box interrupts disablement and re-enablement.
**Work in progress**
* Remote Procedure Call (RPC). New API signatures have been published.
* The alpha-level implementation will follow soon.
**Deprecated features**
* Secure gateway. Cross-box communication will be implemented with RPC
* gateways.
**Bugfixes**
* Several ARMv7-M-specific bug fixes.
* Fixed a bug that sent the device into lock-up after a hard fault.
* Fixed checks on revision numbers for Cortex-M devices.
**Miscellaneous improvements**
* Optimized memory protection for ARMv7-M devices with shared SRAM.
* Build artifacts are grouped into the target/build
* option/configuration-specific folder.
* Documents have been grouped into API vs. core documents.
* Improved style and consistency.
Beetle board is built to optimize power consumption therefore does not
provide on-board LEDs.
This patch adds a comment in PinNames in order to clarify that the
Emulated LEDs are provided for compatibility reasons with the MBED test
suite.

With this change, we check for all-1s before executing erase. This means that
the cost of erasing a range is now proportional to the amount of sectors which
have been programmed. This should result in latency improvements in our use of
containers based on flash storage.
The RWW fix is controversial because it requires holding off interrupts for
periods of around 5ms at a time. But there were still some minor improvements
around that change which could be retained. This commit contains these
changes.
