This patch adds i.MX95 SoC and clock related code. Because they are
based on SCMI, put them in the scmi subfolder.

testing.

SCMI power domain management protocol is supported on sandbox
for test purpose. Add fake agent interfaces and associated
power domain devices.

Adding SCMI base protocol makes it inconvenient to hold the agent instance
(udevice) locally since the agent device will be re-created per each test.
Just remove it and simplify the test flows.
The test scenario is not changed at all.

In sandbox scmi agent, channels are not used at all. But in this patch,
dummy channels are supported in order to test protocol-specific channels.

Updates sandbox SCMI clock driver and tests since enabling CCF will
mandate clock discovery that is all exposed SCMI clocks shall be
discovered at initialization. For this reason, sandbox SCMI clock
driver must emulate all clocks exposed by SCMI server, not only those
effectively consumed by some other U-Boot devices.

Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2)
and sandbox SCMI clock consumer driver gets 2 of them.

As per DT bindings since Linux kernel v5.14, the device tree can define
only 1 SCMI agent node that is named scmi [1]. As a consequence, change
implementation of the SCMI driver test through sandbox architecture to
reflect that.

This change updates sandbox test DT and sandbox SCMI driver accordingly
since all these are impacted.

Fix inline comments and empty line in scmi driver and test files.

Remove test on IS_ENABLED(CONFIG_*_SCMI) in test/dm/scmi.c since these
configuration are expected enabled when CONFIG_FIRMWARE_SCMI is enabled

Add tests for SCMI reset controllers. A test device driver
sandbox-scmi_devices.c is used to get reset resources, allowing further
resets manipulation.

Change sandbox-smci_agent to emulate 1 reset controller exposed through
an agent. Add DM test scmi_resets to test this reset controller.
