[PATCH v2] dt-bindings: remoteproc: k3-dsp: correct optional sram properties for AM62A SoCs

[Hari Nagalla]

The C7xv-dsp on AM62A have 32KB L1 I-cache and a 64KB L1 D-cache. It
does not have an addressable l1dram . So, remove this optional sram
property from the bindings to fix device tree build warnings.

Changes from v1 to v2:
*) Kept back memory-regions property, as it is unrelated to this patch
   correcting the sram property for AM62A C7xv-dsp nodes.

Please use allOf (move top one to bottom) and define separate ifs for
each variant instead of nesting them.
