Samuel Holland 446fa65eb5 lib: sbi_ipi: Process self-IPIs in sbi_ipi_send() ...

An IPI sent to the local hart can be processed directly instead of
triggering the IPI device. This is more efficient, and it avoids a
deadlock when the .sync callback is defined. Since interrupts are
disabled while handling an ecall, the IPI would not get delivered
until the next mret, but sbi_ipi_sync() is called before then.
