Convert the fu540 and fu740 devicetrees to use the new properties
"riscv,isa-base" & "riscv,isa-extensions".
For compatibility with other projects, "riscv,isa" remains.

The 32-bit memory resource is needed for non-prefetchable memory
allocations on the PCIe bus, however with some cards (such as the
SM768) the system fails to allocate memory from this.
Checking the allocation against the datasheet, it looks like there
has been a mis-calcualation of the resource for the first memory
region (0x0060090000..0x0070ffffff) which in the data-sheet for
the fu740 (v1p2) is from 0x0060000000..0x007fffffff. Changing
this to allocate from 0x0060090000..0x007fffffff fixes the probing
issues.

The fu740 has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.

We currently change the macro name for fu540 and fu740 by adding the
prefix respectively, these marcos are referenced by some device nodes,
they should be modified as well.

To improve human readability and enable automatic validation, the tuples
in the various properties containing interrupt specifiers should be
grouped.
Fix this by grouping the tuples of "interrupts" and
"interrupts-extended" properties using angle brackets.

The order of interrupt numbers is incorrect.
The order for FU740 is: DirError, DataError, DataFail, DirFail
From SiFive FU740-C000 Manual:
19 - L2 Cache DirError
20 - L2 Cache DirFail
21 - L2 Cache DataError
22 - L2 Cache DataFail

Add initial support for the SiFive FU540-C000 SoC. FU740-C000 is built
around the SiFIve U7 Core Complex and a TileLink interconnect.
This file is expected to grow as more device drivers are added to the
kernel.
