Remove RISC-V irqchip custom definitions in hotplug.h:
 - CPUHP_AP_IRQ_RISCV_STARTING
 - CPUHP_AP_IRQ_SIFIVE_PLIC_STARTING

For coding convention.

I'm going to assume this is going in through an irqchip tree, but LMK if you
want me to take it via mine.  This isn't really my sort of thing, so I'd prefer
at least an Ack.

Thanks!
