reset: add sandbox test for bulk API

This patch adds the bulk reset API tests for the sandbox test suite.

Unlike the main test, it also check the "other" reset signal using the bulk API
and checks if the resets are correctly asserted/deasserted.

To allow the bulk API to work, and avoid changing the DT, the number of resets
of the sandbox reset controller has been bumped to 101 for the "other" reset
line to be valid.
