Prevent mismatch between _owner and peripheral configuration. In the previous
implementation, the following code would leave the peripheral in an inconsistent
state:
```
SPI spi1(...); // _owner is NULL, peripheral config is 1
spi1.transfer(...); // _owner is 1, config is 1
SPI spi2(...); // _owner is 1, config is 2
spi1.transfer(...) // 1 thinks it still owns peripheral, doesn't reconfigure
```
This patch adds BLE Cordio support into MBED HAL. It contains:
* Cordio and TRIM object files
* The Cordio stack header file
* The Cordio library for Beetle Systems precompiled for GCC and ARMCC
The BLE implementation will be provided in a future patch in the mbed-os
repository.

This patch adds BLE Cordio support into CMSIS. It provides:
* A modification for the linker scripts for both ARMCC and GCC
compilers that adds the cordio specific sections.
* A method to access the Flash stored MAC Address.
The CORDIO_RO_2.1.o and TRIM_2.1.o objects that rappresent the Cordio
firmware will be added by a future patch.

- changing device.h -> targets.json after rebase
- adding startup and config files for ARM_STD toolchain
- changing all STM32F7xx targets to ARM as default toolchain (instead of uARM before)
- nrf headers synchronized with the one in BLE implementation. This is a
short term fix. The nordic branches use a single nrf SDK and does not
have duplicate headers. Once this branch will be integrated, there will
be no more issues around duplicate headers.
- enable feature BLE in the targets.json. This fix was done a long time
ago in the nordic branch. Without it, it is not possible to compile BLE
examples.
Issue #2074
Assuming that OverSampling is initialized, the baudrate is now correctly
computed inside CMSIS (STM32 HAL) layer. This was not the case before but
most probably was fixed during latest L0 cube firmware upgrade:

This is a hack to get debug builds applications that use uVisor to work.
The assertions in core_util_critical_section fail because interrupts can't
actually be disabled from unprivileged mode.
Without this hack, core_util_critical_section_enter() calls
mbed_assert_internal() when the assertion fails, which calls
core_util_critical_section_enter() again, which calls
mbed_assert_internal() again; this is infinite recursion.
core_util_critical_section_enter needs some fixing.
If you don't specify the start address of a section explicitly, that
section can end up at different addresses depending on its alignment. If
the alignment of a section is not explicitly set, it inherits it from
the element with the highest alignment inside that section.
Since the uVisor code is in the .text section, and it *must* end up at a
known location, we set the start address of .text to 0x410, which is the
value that the uVisor binary expects.

in Timers (UPDATE Irq and OutputCompare Irq). The update priority needs to
be higher to avoid undefined behaviours.

Add a virtual destructor to classes which have a virtual lock and
unlock. Remove the virtual qualifier from functions in
InterruptManager since this class cannot be extended.
When the malloc lock and unlock functions are inside a library they
conflict with the standard libraries weak version of these functions.
This is because of the way weak references are handled by the linker.
This patch renames the lock and unlock functions defined inside RTX
so they do not conflict. A thunk inside retarget.cpp then calls the
RTX functions. This problem does not occur with retarget.cpp since
it is always build into an object file rather than a library file.
This is backwards-compatible with unsupported targets.
If an application is compiled using the K64F target without uVisor
(UVISOR_PRESENT not set or set to 0) then uvisor_init() will just be an
empty function that immediately returns.
