Fix also some Chinese GB18030 -> UTF-8 encoding problems

(translated the Chinese strings to English):
修改 -> modification
port8~port10的设置在另外一个register ->
 port8~port10 setup is done in a separate register

You are in the correct (UTF-8) encoding when you see:
 * $Date: 2017-03-08 15:13:58 +0800 (週三, 08 三月 2017) $
e.g. week 3, 08 third month, 2017
But not if you see:
 * $Date: 2017-03-08 15:13:58 +0800 (閫变笁, 08 涓夋湀 2017) $

rtl8367c/rtl8367c_asicdrv_lut.c should be read as UTF-8, despite having
some earlier Chinese text lost to GB18030 encoding.

Improves indexing and searches
