[PATCH v1 2/5] irqchip: starfive: Convert the word "jh8100" to "jhb100"

The StarFive JH8100 SoC was discontinued before production. The
newly taped-out JHB100 SoC uses the same interrupt controller IP.
Rename the driver file, Kconfig symbol, and internal references
from "jh8100" to "jhb100" to accurately reflect the supported
hardware.
