reset: Add sandbox tests for reset_reset() and reset_reset_bulk()

Browse Source 
Add DM test coverage for the new reset_reset() and reset_reset_bulk()
API functions.
The sandbox reset driver implements rst_reset so these tests exercise that
op (not the assert/udelay/deassert fallback in reset_reset()).
reset_reset_bulk() calls reset_reset() on each bulk entry in order, so each
line's rst_reset runs in sequence.
