[PATCH 0/3] mfd: syscon: Cleanup, fix race condition and remove platform driver

Questions from Krzysztof and a syscon related binding review got me
looking at the syscon "driver". This series is the result.

This short series drops the stale platform driver part of syscon
support, fixes a race condition in device_node_get_regmap()
which is used by all the lookup functions, and allows for registering
nodes without "syscon" compatibles.

Compile tested only. Testing on Tensor, the one user of
of_syscon_register_regmap(), would be helpful.
