Let's change the default value to 1 meaning that only interrupt source 0 is supported by default and a sanity check in realize().

Unfortunately this is wrong as VIRT_IRQCHIP_NUM_SOURCES should include interrupt source 0 but "riscv,ndev" does not. While we are here, we also fix the comments of platform bus irq range which is now "64 to 96", but should be "64 to 95", introduced since commit 1832b7cb3f64 ("hw/riscv: virt: Create a platform bus").

'opentitan' should have set "priority-base" to 0x04 too. Note the irq number calculation in sifive_plic_{read,write} is correct as the codes make up for the irq number by adding 1. Let's simply update "priority-base" to start from interrupt source 0 and add a comment to make it crystal clear.
