Infinity bootloader change
==========================
After @2c7542e(2015/01) Infinity bootloader doesn't disable watchdog timer and keyboard firmware has to do it itself. mbed disables watchdog in startup sequence but unfortunately timer is timed out bofore that.
We have to do that in earlier phase of mbed startup sequence.

WORKAROUND
----------
Call SystemInit early in Reset_Handler.
