Serge Semin 8450813136 dt-bindings: memory: synopsys,ddrc-ecc: Detach Zynq DDRC controller support
The Zynq A05 DDRC controller has nothing in common with DW uMCTL2 DDRC:
the CSRs layout is absolutely different and it doesn't support IRQs unlike
DW uMCTL2 DDR controller of all versions (v1.x, v2.x and v3.x). Thus there
is no any reason to have these controllers described in the same bindings.
Let's split the DT-schema up.

Note since the synopsys,ddrc-ecc.yaml schema describes the Synopsys DW
uMCTL2 DDR controller only, we need to accordingly fix the device
descriptions.

description:
The Zynq DDR ECC controller has an optional ECC support in half-bus width
(16-bit) configuration. It is cappable of correcting single bit ECC errors
and detecting double bit ECC errors.
