Shun SKNN / Mbed 2 deprecated frdm_mouse_K22F

Ported a code that FRDM-KL46Z act as a USB mouse originally developed by jksoft, to FRDM-K22F. SW2 and SW3 act as left and right buttons respectively because K22F lacks a touch sensor, in contrast to KL46Z.

Dependencies:   FXOS8700Q USBDevice mbed

jksoftさんのUSBマウス(FRDM-KL46Z用)をFRDM-K22Fにポーティング。 KL46Zとは異なり、K22Fにはタッチセンサがありません。このため、SW2を左ボタン、SW3を右ボタンとしています。

Ported USB mouse for FRDM-KL46Z originally developed by jksoft to FRDM-K22F. SW2 and SW3 act as left and right buttons respectively because K22F lacks a touch sensor, in contrast to KL46Z.
