Fix buf name error for "lv_port_disp_template.c" and optimize the arduino example (#2475)

Browse Source 
* fix(buf) correct the name error

* fix(format) make the indent become 4 space

* fix(print) use lv_version_xxx  to serial for debug

* fix(arduino) optimize the code

* fix(arduino) use lv_version_xxx to serial
