Configuration of the local target state management mode, By
definition target can handle read/write transaction as long as it is out
of IDLE state.
0x0 = Force-idle mode: local target's idle state follows
(acknowledges) the system's idle requests unconditionally, i.e.,
regardless of the IP module's internal requirements; Backup mode,
for debug only.
0x1 = No-idle mode: local target never enters idle state, Backup
mode, for debug only.
0x2 = Smart-idle mode: local target's state eventually follows
(acknowledges) the system's idle requests, depending on the IP
module's internal requirements, IP module shall not generate (IRQ-
or DMA-request-related) wakeup events.
0x3 = Smart-idle wakeup-capable mode: local target's idle state
eventually follows (acknowledges the system's idle requests,
depending on the IP module's internal requirements, IP module may
generate (IRQ- or DMA-request-related) wakeup events when in idle
state.
