riscv: sifive_u: Update hart configuration to reflect the real FU540 SoC
The FU540-C000 includes a 64-bit E51 RISC-V core and four 64-bit U54
RISC-V cores. Currently the sifive_u machine only populates 4 U54
cores. Update the max cpu number to 5 to reflect the real hardware,
by creating 2 CPU clusters as containers for RISC-V hart arrays to
populate heterogeneous harts.
The cpu nodes in the generated DTS have been updated as well.
