Subject: [PATCH] RISC-V: Add debug defconfigs

Various Linux kernel DEBUG options have big performance impact
so these should not be enabled in RISC-V normal defconfigs.

Instead we should have separate RISC-V debug defconfigs having
these DEBUG options enabled. This way Linux RISC-V can build both
non-debug and debug kernels separately.
