wls: add cps4019's bootloader download logic

Browse source 
For our designation, cps4019's bootloader FW is a raw data
in head file(https://gerrit.mot.com/#/c/2239690/). So we use
a dts configuration(use_bl_in_h) to distinguish the original
method(using FW file) and ours. If this dts property is defined,
we will use tha raw data in header file.
