 Wrong v3 version, some BIT definition are mixed in patch 1,2. 

V3:
 Addressed Michal's comments.
 Add Henry's T-b

V2:
 Per Julien's comments, fix coding style issue, drop unneeded code

Add i.MX lpuart driver and i.MX8QM platform support.
 - lpuart is the uart IP used in i.MX8QM/QXP/93.
 - Very basic i.MX8QM platform support.
