lib: sbi: Extends sbi_ipi_raw_send() to use all available IPI devices
A platform may contain multiple IPI devices. In certain use cases,
such as power management, it may be necessary to send an IPI through a
specific device to wake up a CPU. For example, if an IMSIC is powered
down and reset, the core cannot receive IPIs from it, so the wake-up must
instead be triggered through the CLINT.
