From: Magnus Damm <damm+renesas@opensource.se>

Hook up SYS-DMAC prototype support for SDHI on Lager.

Local platform device version of SYS-DMAC and local slave IDs
are used together with AUXDATA. CD and WP pins, regulators
and clocks are provided via DT.

Only the DT reference case is covered. Not for upstream merge.
