lib: sbi_ipi: Make .ipi_clear always target the current hart

All existing users of this operation target the current hart, and it
seems unlikely that a future user will need to clear the pending IPI
status of a remote hart. Simplify the logic by changing .ipi_clear (and
its wrapper sbi_ipi_raw_clear()) to always operate on the current hart.

This incidentally fixes a bug introduced in commit 78c667b6fc07 ("lib:
sbi: Prefer hartindex over hartid in IPI framework"), which changed the
.ipi_clear parameter from a hartid to a hart index, but failed to update
the warm_init functions to match.

Fixes: 78c667b6fc07 ("lib: sbi: Prefer hartindex over hartid in IPI framework")
