Subject: [PATCH] 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.

Also set the 'memory-regions' property as optional. This is because
the remote processors can function without carveout regions.
