[PATCH] ASoC: rt286: Add API to set supported jack type

[<bardliao@realtek.com>]

From: Bard Liao <bardliao@realtek.com>

RT286 need to configure the jack type (combo or non-combo) according to the
HW design. This function is given a easy way to set the correct jacy type
for those without platform data supported.
