[EXPORT][NUCLEO_F334R8] export to gcc_arm and coide

- rtos library is not working because of double defined SysTick_Handler
in system_stm32f3xx.c and in rtos
- please see pullrequest #526 for a correct export
- tests are working fine:

[EXPORT][NUCLEO_F334R8] a missing line in export/coide.py
Fix NRF51822 PWM and Serial:
- imlement pwmout_free()
- check UART interrupt type carefully
- implement serial_set_flow_control()
- add serial_clear() stub
[EXPORT][NUCLEO_F334R8] removed accidentally 2 macros

The commit 'export to gcc_arm and coide' removed accidentally 2 macros
from NRF51822 and NRF51 targets.
[DISCO_F429ZI] missing interrupt vectors

Added some missing F429 interrupt vectors
[K64F] Add mbed_mac_address implementation
[DISCO_F429ZZI] pin function definition

Added mostly all pin function (ADC, I2C, SPI, UART, PWM).

The basis of the target was DISCO_F407. The 429 has some additional pin
functions which are added with this commit. Also ports, pins and pin
functions of the larger packages are added not only the available of the
F429ZI package.
