dt-bindings: PCI: renesas,r9a08g045s33-pcie: Fix naming properties

Fix a typo in interrupt-names: "ser_cor" should be "serr_cor" (System
Error Correctable).

Also convert interrupt-names, clock-names, and reset-names properties
from "description" to "const" to enable proper validation with
dtbs_check.

Fixes: e7534e7905 ("dt-bindings: PCI: Add Renesas RZ/G3S PCIe controller binding")
