syscon: dm: Add a new method to get a regmap from DTS
syscon_regmap_lookup_by_phandle() can be used to get the regmap of a syscon device from a reference in the DTS. It operates similarly to the linux version of the namesake function. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
