Problem:
When enumerating device tree nodes, platform bus and native buses (I2C/SPI)
may create duplicate devices for the same OFW node, causing cross-bus conflicts.
This triggers assertion failure '(dev->bus != new_bus)' in
rt_bus_reload_driver_device() during boot on minimal DM-enabled systems.
Root Cause:
1. Platform bus tries to reload devices that already belong to other buses
by calling rt_bus_reload_driver_device(dev->bus, dev), which violates
the API contract (requires dev->bus != new_bus).
2. Native buses (I2C/SPI) do not mark OFW nodes as occupied, so platform
bus creates duplicate platform devices for I2C/SPI client nodes.
Solution:
1. components/drivers/core/platform_ofw.c: Return RT_EOK when np->dev exists,
letting the native bus handle device lifecycle instead of cross-bus reload.
2. components/drivers/i2c/dev_i2c_bus.c: Mark i2c_client_np->dev during scan
to prevent platform bus from duplicating I2C client devices.
3. components/drivers/spi/dev_spi_bus.c: Mark spi_dev_np->dev during scan
to prevent platform bus from duplicating SPI devices.
Tested on Spacemit K1 RISC-V platform with minimal DM configuration.

src/utest/device_tc.c is testing API: rt_device_find(),
which is a function defined in components/drivers/core/device.c.
So it should be a testcase for drivers core, not for core.
Move it to under components/drivers/core.

If a node request a new node or it's parent node. the request's node will probe a double time.
So we check the device object of node in ofw probe entry and ofw probe child exit.
