The fdt_ipi_init() is already called from generic_early_init() so
let's convert IPI drivers as early drivers.

We would like to clean any files generated by the carray
scripts by just searching for the filename as the current
make system turns f.carray into f.o. Change to make the
make system turn f.carray into f.carray.o
note, command to go through .mk files changing the .o
in the .mk files is:
find . -type f -name "*.carray" | xargs -t -I fname /bin/bash -x -c ' fn=`basename -s .carray fname`; echo "$fn"; sed -i `dirname fname `/objects.mk -e s/"$fn".o/"$fn".carray.o/g'

Move Andes PLICSW ipi device to fdt ipi framework, this patch is based
on Leo's modified IPI scheme on PLICSW.
Current IPI scheme uses bit 0 of pending reigster on PLICSW to send IPI
from hart 0 to hart 7, but bit 0 needs to be hardwired to 0 according
to spec. After some investigation, self-IPI seems to be seldom or never
used, so we re-order the IPI scheme to support 8 core platforms.
dts example (Quad-core AX45MP):
plicsw: interrupt-controller@e6400000 {
compatible = "andestech,plicsw";
reg = <0x00000000 0xe6400000 0x00000000 0x00400000>;
interrupts-extended = <&CPU0_intc 3
&CPU1_intc 3
&CPU2_intc 3
&CPU3_intc 3>;
interrupt-controller;
#address-cells = <2>;
#interrupt-cells = <2>;
};

We update ipi drivers makefile to use kconfig for enabling/disabling
drivers. To avoid compile errors, we also enable appropriate ipi
drivers for each platform.

Instead of having FDT ipi driver list hard-coded in the C source,
we generate it using carray.sh at compile-time.

CLINT device and standalone ACLINT MSWI device.

We add common ACLINT MSWI library similar to the CLINT library
so that OpenSBI platforms can use it.
