PM / shmobile: Don't include SH7372's INTCS in syscore suspend/resume
Since the SH7372's INTCS in included into syscore suspend/resume, which causes the chip to be accessed when PM domains have been turned off during system suspend, the A4R domain containing the INTCS has to stay on during system sleep, which is suboptimal from the power consumption point of view. For this reason, add a new INTC flag, skip_syscore_suspend, to mark the INTCS for intc_suspend() and intc_resume(), so that they don't touch it. This allows the A4R domain to be turned off during system suspend and the INTCS state is resrored during system resume by the A4R's "power on" code.
