Changed the Arduino tests order
Fixed Freescale byte reads (minus k64)

See:
https://mbed.org/questions/3181/Inconsistent-results-when-attempting-wri/
for the issue. Now every byte read is treated equal and ACKs/NACKs are
correctly generated
I2C changes for the K64F

Fixed also here single byte read (probably)
Added D14, D15 pins for LPC812
K64F - i2c fix, debug-info sets optimization to

	- debug-info for all toolchains set optimization to 0
	- i2c - open drain and clock enabled for i2c pins [K64F]
K20 - i2c open drain enabled
[NUCLEO_F401RE] Add auto clock configuration (HSE/HSI)

Solve also the problem with the SetSysClock function not declared in
sleep.c
