HV: include: integral type cleanup

Browse Source 
This patch cleans up the integral type violations to MISRA C rules, mostly
related to signed constants that should be unsigned but also spelling out two
integer narrowing and dropping some macros negating unsigned integers.

v1 -> v2:

    * Drop INT_ROUNDUPx macros since they are never used.
