hw/intc: sifive_plic: Change "priority-base" to start from interrupt source 0

At present the SiFive PLIC model "priority-base" expects interrupt
priority register base starting from source 1 instead source 0,
that's why on most platforms "priority-base" is set to 0x04 except
'opentitan' machine. '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.

hw/riscv: virt: Fix the value of "riscv, ndev" in the dtb

Commit 28d8c281200f ("hw/riscv: virt: Add optional AIA IMSIC support to virt machine")
changed the value of VIRT_IRQCHIP_NUM_SOURCES from 127 to 53, which
is VIRTIO_NDEV and also used as the value of "riscv,ndev" property
in the dtb. 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").
