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.

The target_hart and hartid paramter of TIMER callbacks is not
required because it always current hartid which can be obtained
using sbi_current_hartid() API.

The source_hart and hartid parameter is really not required in
IPI callbacks of sbi_platform because current hartid can always
be obtained by calling sbi_current_hartid() API.

Avoid using standard includes namely stdint.h, string.h, stdlib.h, etc.
All standard include except stddef.h give compilation error due
to differences in RISC-V toolchain configuration. Typically, the
compilation error is related to "gnu-stubs-lp64.h".
This patch fixes compile error caused by standard includes by
providing substitutes of definetions provided by standard includes
wherever required.

PLIC DT entry fixup can be done by comparing external
interrupt number instead of context id. No need to invoke
fixup for each plic context.

There are couple of string function defined in platform
code. We no longer need them as we can directly link minimal
libc.
Every platform required to inclde this as PLIC driver required
libc functions.

Some of the platform (i.e. SiFive FU540) requires Device
Tree modification before it is passed to higher stages.
Add libfdt support now to help this process. Libfdt should
only be included per platform basis.

PLIC register base calculation is current wrong because of that.
