Remove superfluous JTAG disable code (#6445)
* Remove superfluous JTAG disable code * 32A has differently named register * Accidentally some operators * 32A also has different JTAG pins * Wrap disable_jtag() in an ifndef * Document this new define * Rename the define, it conflicts with a LUFA thing Also, move the ifndef wrapping to the call in keyboard_setup()

-## 在USB AVR使用PF4-7针脚?
-你要置位MCUCR寄存器JTD位来将PF4-7设置为GPIO。这些针脚默认是JTAG功能。 像ATMega*U* or AT90USB*这样的MCU会受影响。
-
-如果是用Teensy的话就不需要了。Tennsy自带JTAGEN位未编程来失能该功能。
-<!--翻译问题:上句可能有错,原文为:Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function. -->
-代码如下。
-```
- // F接口JTAG失能。在四个周期内写入两次JTD位。
- MCUCR |= (1<<JTD);
- MCUCR |= (1<<JTD);
-```

-阅读ATMega32U4的datasheet中的**26.5.1 MCU Control Register – MCUCR**。
