lib: tests: add math test suite

Browse Source 
This patch introduces a new math test suite to the SBI unit
tests. The changes include:

* Updating lib/sbi/tests/objects.mk to include
  math_test_suite and sbi_math_test.o.
* Adding a new file lib/sbi/tests/sbi_math_test.c which
  contains tests for log2roundup function using various cases.

The addition of this test suite ensures that mathematical
functions are verified and work as expected.
