Subject: [PATCH v3] dt-bindings: remoteproc: k3-dsp: correct optional sram properties for AM62A SoCs

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 in v3:
*) Use allOf keyword with separate ifs for each variant instead 
   of nested if/else conditions.
