libsbi needs some of the custom libc functions. It should be directly
included in libsbi instead of platform specific libraries.

The codes that currently program the interrupt enable register for
S-mode disagrees with what the comments say. Fix the comments.
While we are here, add one line comment to describe what is done
for M-mode too.

At present plic_set_priority() ignores the 'source' and the priority
register to be programmed is constant. Fix it.

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.

Unleashed doesn't have S mode for hart 0.
PLIC register base calculation is current wrong because of that.
