#define	CPU_DEFAULT_IRQ_PRIO   1u
	Default IRQ priority for the CPU, we don't have different levels at the moment.
#define	CPU_IRQ_NUMOF   52u
	The RP2350 has 52 IRQs, see cpu/common/rp2350/vectors.c for more details.
#define	RP2350_USE_RISCV   1
	This tells cpu/common/rp2350 that we are using the RISC-V core.
#define	CPU_CYCLES_PER_LOOP   2
	CPU cycles per busy wait loop, due to branch prediction the Hazard3 executes the busy_wait() loop (addi + bnez) in only two cycles.
