mmc: Explicitly include correct DT includes
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.

This is caused by:
platform_device_register()
-> platform_device_unregister(to_platform_device(dev))
freeing struct device
-> of_node_clear_flag(dev->of_node, ...)
writing to the freed device
The issue is solved by increasing the reference count before calling
of_platform_device_destroy() so freeing the device is postponed after
the call.

mmc: cavium: Fix probing race with regulator
If the regulator probing is not yet finished this driver
might catch a -EPROBE_DEFER. Returning after this condition
did not remove the created platform device. On a repeated
call to the probe function the of_platform_device_create
fails.
Calling of_platform_device_destroy after EPROBE_DEFER resolves
this bug.

This is caused by:
platform_device_register()
-> platform_device_unregister(to_platform_device(dev))
freeing struct device
-> of_node_clear_flag(dev->of_node, ...)
writing to the freed device
The issue is solved by increasing the reference count before calling
of_platform_device_destroy() so freeing the device is postponed after
the call.

mmc: cavium: Fix probing race with regulator
If the regulator probing is not yet finished this driver
might catch a -EPROBE_DEFER. Returning after this condition
did not remove the created platform device. On a repeated
call to the probe function the of_platform_device_create
fails.
Calling of_platform_device_destroy after EPROBE_DEFER resolves
this bug.
