xtensa: drop ARCH_WANT_FRAME_POINTERS
ARCH_WANT_FRAME_POINTERS was enabled in the xtensa Kconfig in the commit
8f371c7521
("xtensa: enable lockdep support"), but neither windowed
nor call0 xtensa ABI need frame pointers for stack tracing.
Drop ARCH_WANT_FRAME_POINTERS from the xtensa Kconfig.
Drop ftrace_return_address0 definition as the generic implementation is
correct.
