riscv: irq: Set prio for dynamic and direct irqs on clic

The irq priority has to be called for dynamic and direct irqs, too. For
direct isrs, this was missing completely, for direct irqs just for the
clic.

For dynamic irqs, I replaced the current implementation with
`z_riscv_irq_priority_set`. For the plic, this is exaclty the same.
