[PATCH 02/13] dt-bindings: memory: snps: Add Baikal-T1 DDRC support

Baikal-T1 DDR controller is based on the DW uMCTL2 DDRC IP-core v2.51a
with up to DDR3 protocol capability and 32-bit data bus + 8-bit ECC. There
are individual IRQs for each ECC and DFI events.The dedicated scrubber
clock source is absent since it's fully synchronous to the core clock.
In addition to that the DFI-DDR PHY CSRs can be accessed via a separate
registers space.
