446a9c6d1e lib: utils: Allow PLIC functions to be used for multiple PLICs
We extend all PLIC functions to have a "struct plic_data *"
parameter pointing to PLIC details. This allows platforms to
use these functions for multiple PLIC instances.

73d6ef3b29 lib: utils: Remove redundant parameters from PLIC init functions
The "target_hart" and "hart_count" parameters of PLIC cold and
warm init functions are only used for sanity checks and not
required in PLIC initialization.

a9eac67ad0 include: sbi_platform: Combine reboot and shutdown into one callback
We can achieve shutdown, cold reboot, and warm reboot using just
one sbi_platform callback so we combine system_reboot() and
system_shutdown() callbacks into one system_reset() callback.

1bb00ab3ae lib: No need to provide default PMP region using platform callbacks
The default (usually last) PMP region provides S-mode access to
complete memory range not covered by other PMP regions.

Currently, the default PMP region is described as platform specific
PMP region which is not appropriate because all platforms need it
and default PMP region should be part of generic library.

fdt_helper.c and rename it to fdt_plic_fixup() at the same time,
to keep name consistency in the same file.

72a0628c7e platform: Use one unified per-HART stack size macro for all platforms
As of today all platforms use 8KB of per-HART stack hence there is
no need for each platform to define its own macro or use the magic
number. Create one macro for all platforms. Platform still can use
its own version if needed.

823345ecae include: Make sbi_current_hartid() as macro in riscv_asm.h
The sbi_current_hartid() being a regular function is quite
expensive because for callers it is a function call instead
of a direct CSR read. This patch converts sbi_current_hartid()
into a macro in riscv_asm.h.
