The pm_policy_state_lock_put and pm_policy_state_lock_put functions
already become a no-op if CONFIG_PM is not enabled. Drop the guards
around it in few different drivers.

Introduce SMARTDMA dma driver. The SMARTDMA is a peripheral present on
some NXP SOCs, which implements a programmable DMA engine. The DMA
engine does not use channels, but rather provides a series of API
functions implemented by the firmware provided with MCUX SDK.
These API functions can be selected by the dma_config slot parameter. A
custom API is also provided to allow the user to install an alternate
firmware into the SMARTDMA.
