f9e1600b28 McHCK now working with UART.
- Lots of code cleanup for the intialization of all arm chips
- Added more gcc flags to help with debugging linker and memory map
- Fixed UART initialization for the smaller MCHCK mk20dx128 (different pin mux)

0365d517fe Fixed bug with standalone UART CLI
- Sending characters to the UART before it's ready would overflow the buffer causing it to hang
- Added a check to make sure the interface is ready before starting to send characters
- Removed the incorrect check for the usbMuxUart to make sure usb is ready before sending over the uart
