[PATCH v2 19/24] hw/riscv: pfsoc: Fix Icicle Kit hart count at five

[Bin Meng <bin.meng@processmission.com>]

The Icicle Kit always contains one E51 management hart and four U54
application harts. The model currently accepts two to five harts and
defaults to two, allowing configurations that cannot match the board.

Set the minimum and default CPU counts to the five-hart maximum.
Update the documentation to state that other hart counts are rejected.
