Subject: [PATCH 0/6] Add rounding macros and enable KUnit tests

This adds new rounding macros to round to closest integer along with
enabling KUnit tests for all math.h macros.  It also updates kernel-doc to
render math.h related documentation and lastly updates the imagination jpeg
encoder to use the newly introduced rounding macros to find nearest value.

Also to note that math.h is orphaned and so these changes need
to be pulled by subsystem using it as a first as discussed in below
threads:
