Now that we have a dedicated fdt_helper.c file for DT releated
helper routines, move plic_fdt_fixup() codes from plic.c to
fdt_helper.c and rename it to fdt_plic_fixup() at the same time,
to keep name consistency in the same file.

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.

Recent commit
4a603eb ("platform: kendryte/k210: Set per-HART stack size to 8KB")
forgot to update ariane-fpga codes, and the following commit
678c3c3 ("include: sbi_scratch: Set per-HART scratch size to 4KB")
changed the per-HART scratch size to 4KB, which potentially breaks
ariane-fpga platform.
This patch set per-HART stack size of ariane-fpga to 8KB for consistency.

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.

The disabled_hard_mask in sbi_platform is only 64bits wide so we
cannot disable a HART with HARTID > 63. To tackle this, we remove
disabled_hart_mask and replace it with hart_disabled() platform
callback.

It is possible to have a CLINT implementation which supports
only 32bit MMIO accesses on RV64 system so this patch extends
our CLINT driver such that platform code can specify whether
CLINT supports 64bit MMIO access.

OpenSBI manages outstanding TLB flush requests by queueing
them in a fifo synchronously. An ipi sync which uses an
atomic operation on MMIO address is no longer required.
Remove the ipi sync method from platform header and all usage.

We needed to enable PLIC interrupts early(like on BBL) due to some issue of the design.
Otherwise, Linux would not get any external interrupts.
