[PATCH v4 0/5] reset: Introduce reset_reset.*() API

[Michal Simek <michal.simek@amd.com>]

Hi,

the patchset is adding reset_reset.*() interface which is common
in Linux. And implement it for ZynqMP.

Thanks,
Michal

Changes in v4:
- change reset test logic

Changes in v3:
- extend function documentation
- align commit message with implementation
- new patch in series

Changes in v2:
- Add delay_us parameter to specify delay between assert and deassert
- Pass delay_us to rst_reset op so drivers can use it if needed
- Return -ENOSYS in stubs when !CONFIG_DM_RESET (like clk.h)
- Fix line length to stay within 80 characters
- Add reset_count field to track reset pulse operations
- Implement sandbox_reset_reset() for rst_reset op
- Add sandbox_reset_get_count() to query reset pulse count
- Clear reset_count when reset is requested
- Update tests to verify reset pulse actually happened
- Pass 10us via parameter
