Subject: [PATCH v2] RISC-V: Enable profiling by default

Let us enable profiling by default in RV32 and RV64 defconfigs so
that we can use RISC-V PMU drivers on various RISC-V platforms.

Signed-off-by: Anup Patel <[email protected]>
---
Changes since v1:
- Enable CONFIG_PROFILING instead of CONFIG_PREF_EVENTS in defconfigs
