riscv: remove special treatment for the link order of head.o

commit 2348e6bf44213c5f447ff698e43c089185241ed7 upstream.

arch/riscv/kernel/head.o does not need any special treatment - the only
requirement is the ".head.text" section must be placed before the
normal ".text" section.

The linker script does the right thing to do. The build system does
not need to manipulate the link order of head.o.
