asoc: msm: More MBHC tunings!

 * All day every day!
 * It seems that certain OEM handset makers who are also in the
   accessory biz have chosen resistence values which lie directly
   on the threshold of the reference design. I can only think of
   a few reasons why someone would do this.
 * Nice trolling, Xiaomi :)

asoc: msm: MBHC tunings forever!

 * Franco's Apple headset is right on the boundary for HIGH_HPH.
 * Move the threshold down to 180.
