This commit solves issue related to i2c driver performance.
With this commit delay in read write when using i2c timing
algorithm is solved. Used flag mechanism which will check
tim reg value and hz passed.

This commit solves excess usage of RAM. User can now enable/disable
I2C timing algorithm. Disabling of I2C timing algorithm would
reduce RAM usage.

Modified i2c_device.h file. This will solve I2C read
write long time issue. Updated default I2C peripheral clock
value to 160MHz.

This commit adds I2C timing value automatic calculation algorithm
for all supported families added. This patch improves I2C timing calculation
according to I2C input clock and I2C bus speed.
This commit also allows user to change the system clock and I2C input clock.

dac_write (used by AnalogOut.write) calls HAL_DAC_Start
every time. It is required to call HAL_DAC_Start only once.
HAL_DAC_Start uses internally HAL_Delay(1) making AnalogOut
not suitable for use in high speed application.
This change removes call to HAL_DAC_Start in dac_write and
moves it to analogout_init.
Refactor all ST targets to be CMake buildsystem targets. This removes
the need for checking MBED_TARGET_LABELS repeatedly and allows us to be
more flexible in the way we include MBED_TARGET source in the build.
A side effect of this is it will allow us to support custom targets
without breaking the build for 'standard' targets, as we use CMake's
standard mechanism for adding build rules to the build system, rather
than implementing our own layer of logic to exclude files not needed for
the target being built. Using this approach, if an MBED_TARGET is not
linked to using `target_link_libraries` its source files will not be
added to the build. This means custom target source can be added to the
user's application CMakeLists.txt without polluting the build system
when trying to compile for a standard MBED_TARGET.
