[PATCH] arm64: dts: qcom: taoyao: Drop adsp_rpc_remote_heap_mem override

[Stanislav Zaikin]

taoyao originally redefined adsp_rpc_remote_heap_mem at a fixed address
to avoid overlapping with cdsp_mem, since kodiak.dtsi's version was a
fixed-address at the time.

kodiak.dtsi now defines adsp_rpc_remote_heap_mem as a dynamically
allocated "shared-dma-pool" region instead, which removes the fixed
address entirely and so cannot overlap with cdsp_mem. This makes the
override unnecessary.

Remove the taoyao-local /delete-node/ and static reg-based redefinition,
and inherit the definition from kodiak.dtsi instead.

Fixes: 28705df5d0df ("arm64: dts: qcom: sm7325: Add Xiaomi 12 Lite 5G (taoyao) DTS")
