RISC-V: Remove unused print_ext_doc_entry function [NFC]

The print_ext_doc_entry function and associated version_t struct in
gen-riscv-ext-opt.cc were not being used anywhere in the codebase.
Remove them to clean up the code.

gcc/
	* config/riscv/gen-riscv-ext-opt.cc (version_t): Remove unused
	struct.
	(print_ext_doc_entry): Remove unused function.
