Bin Meng e921fc2691 platform: plic: Fix comments of programming the interrupt enable register
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.

Bin Meng 312850148a platform: plic: Bypass interrupt ID 0's priority programming
Per PLIC spec, interrupt ID 0 is defined to mean "no interrupt".
We should bypass it.

Anup Patel ebfe231256 platform: Fix compile error caused by standard includes
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.

Atish Patra e0686ca844 platform: No need to pass context id for plic fixup.
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.

Atish Patra 00f77d9ba0 platform: Remove string functions from tinyfdt.c
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.
