[PATCH v2 3/3] checkpatch: relax Kconfig help text line number threshold

[Yingjoe Chen]

Current threshold is too strict and many upstream patch doesn't pass
this test. Relax it.

In v4.6-rc1, 171 new config options was added, and 87 of those options
have < 4 lines and 24 options have only 1 line. After this change,
checkpatch only raise warning when help text only contain 1 line.

Some options try to workaround this check by adding 2 lines
template like 'If you have this device...' which doesn't add value.
