The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

'ret' is known to be 0 here.
The expected error status is stored in 'status', so use it instead.
Also change %d in %u, because status is an u32, not a int.

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.

We've saved the double data flag in the device data, so we should
use it when programming a block.

We have some cases that will programme the eFuse block partially multiple
times, so we should allow the block to be programmed again if it was
programmed partially. But we should lock the block if the whole block
was programmed. Thus add a condition to validate if we need lock the
block or not.
Moreover we only enable the auto-check function when locking the block.

According to the Spreadtrum eFuse specification, we should write 0 to
the block to trigger the lock operation.

The Spreadtrum eFuse controller is widely used to dump chip ID,
configuration setting, function select and so on, as well as
supporting one-time programming.
