Bogdan Marinescu faee2bf073 [NUCLEO_F103RB] Serial interrupt fixes 
- use TC flag instead of TXE for TX interrupt
- clear interrupt flags to prevent possible interrupt storm

Bogdan Marinescu 2b8e05e002 [NUCLEO_F103RB] Timer fixes 
- the timer data structures were not properly initialized
- changed slave timer mode to external clock 1 (section 15.3.15 of the manual)
- avoid a possible race condition when concatenating the values of the
  two 16-bit timers

Sissors 9f89a4d218 Added (deep)sleep to KL25Z 
Sleep is wait mode

Deepsleep is very low power stop mode

During the interrupt that removes it from deepsleep it will run at low
speed until the PLL is automatically re-enabled after the interrupt.

Michael Moon a249e39826 Improved baudrate calculation function. 
Uses 100% integer math, delivers more accurate results with fewer iterations in less time.

Since it seems most of the NXP chips use identical math, I have also altered the other targets in this commit.

If there are non-NXP chips which use a similar serial block, consider porting to those as well

Adam Green 969733ae8f serial_putc() to make better use of Tx FIFO 
If don't know if this is an issue that anyone cares about.  I am also
not sure what the best way to solve it is either.  I just thought I
would issue a pull request with this commit to bring the issue to light
and show a possible solution that I have tested on my mbed-1768 device.

Previously the serial_putc() API didn't make any use of the Tx FIFO
since the serial_writable() API it utilizes only returns true when the
FIFO is completely empty.  This is due to the fact that the THRE bit of
the UART's LSR (Line Status Register) only goes high when the whole
FIFO is empty.

I noticed this when doing some performance testing with the network
stack.  I went from calling printf() to output 3 bytes every 10 seconds
(with packet drop stats) to instead output 4 bytes every 10 seconds.
I thought these should easily fit in the 16 byte FIFO but outputting
one extra byte caused an additional three 550 byte UDP packets to be
dropped.  This should only happen if the additional character being
sent to the UART was taking away extra CPU cycles from the network
stack.

My solution is to keep track of the number of bytes that have been
placed in the Tx FIFO since it was last detected as being completely
empty (via the THRE bit).  Only once this count hits 16 does the code
then block, waiting for the THRE bit to go high.  Each time the THRE
bit does go high, the count is reset to 0 again and it is incremented
for each byte that is loaded into the THR.

Bogdan Marinescu 544ac9e728 Disable DEVICE_STDIO_MESSAGES for LPC81X 
Because the LPC81X HAL implementation calls error(), which in turn calls
fprintf(), quite a bit of code is added to the image, which is not a good
idea on such resource constrained targets.

Joris Aerts 7ed6acb08a Move pwmout_api.c/PeripheralNames.h to LPC11XX_11CXX common 
Because CT32B1 (P1_1, P1_2 and P1_3) is used by us_ticker.c for wait and ticker function. Since wait/ticker is commonly used by mbed code and I decided CT32B1 of LPC11XX should only be used for this function, not for PwmOut.
P1_6 and P1_7 are used by UART (USBTX/USBRX) and I think they should not be assigned to other function.
