ipq806x: fix tsens driver in 4.19

Browse Source 
Added patch:

 - 063-3 Fix tsense shared memory problem

Recent changes in ioremap_resource function are causing fails for the
memory areas which are already mapped. This changes are causing tsense
driver failures during initialization:

  qcom-tsens 900000.thermal-sensor: tsens init failed

So this patch uses simple ioremap in order to use this shared memory
space.
