Kevin O'Connor 45cd3543e3 lpc176x: Use full peripheral clock speed; fix UART interface 
Commit ae89a659 caused a regression in the lpc176x UART handling.
After that commit the UART clock divisor would need to be 6.25 on
lpc1768 or 7.5 on lpc1769, but the code only supports whole numbers.

Set the PCLKSELx registers at startup and return to using full speed
peripheral clocks.

Kevin O'Connor ccb8db5ea1 lib: No need to make lpc176x SystemInit() externally visible 
Now that the lpc176x code uses the armcm_boot mechanism, it is no
longer necessary for SystemInit to be externally visible.
