fuyuno sakura / Mbed 2 deprecated lpclcd

Hello world for lpclcd module https://strawberry-linux.com/catalog/items?code=12014

Dependencies:   I2cLCD mbed

Program "lpclcd" sample via USB Bootloader using offline uVision toolchain(MDK)

NXP USB Bootloader needs checksum. if you use MDK, needs extra command to create checksum before create .bin file.

You must add project option's "Run User Program After build" section,

 $K\ARM\BIN\ELFDWT.EXE !L

see http://www.keil.com/support/docs/3592.htm and http://www.keil.com/support/man/docs/uv4/uv4_ut_elfdwt.htm

If you create .bin on mbed online compiler, or program via JTAG(SWD), this process(option) is not needed.
