In case of FIFO is empty, return -1 as per the specification.

025d0ae994 include: Rename ipi_inject() to ipi_send() for sbi_platform
For better naming, we rename ipi_inject() to ipi_send() in
struct sbi_platform. We also replace term "inject" with
"send" in all related places.

36394d2f24 include: Drop MMIO from SBI_PLATFORM_HAS_MMIO_TIMER_VALUE
It is not necessary that platform has MMIO-based timer value
register. It can also have some custom (implementation specific)
CSR for timer value.

This patch renames SBI_PLATFORM_HAS_MMIO_TIMER_VALUE to
SBI_PLATFORM_HAS_TIMER_VALUE to imply "platform timer value"
instead of "mmio timer value".

52ed1d1709 lib: Simplify sbi_platform timer_init() hooks
Instead of having separate timer_init() hooks for cold and
warm boot, this patch updates struct sbi_platform to have just
one timer_init() hook. The type of boot (cold or warm) is now
a boolean flag parameter for the updated timer_init() hook.

88b173b33b Introduce hart disabled parameter in platform.
As of now, uboot doesn't have support for SMP.
Moreover, unleashed board has a E51 hart which
doesn't not support S mode.

We should only boot only 1 non-zero hart.
