riscv: Remove non-standard linux,elfcorehdr handling
RISC-V uses platform-specific code to locate the elf core header in memory. However, this does not conform to the standard "linux,elfcorehdr" DT bindings, as it relies on a reserved memory node with the "linux,elfcorehdr" compatible value, instead of on a "linux,elfcorehdr" property under the "/chosen" node. The non-compliant code can just be removed, as the standard behavior is already implemented by platform-agnostic handling in the FDT core code.
