ve shared interrupt flag, because we're are an interrupt controller now, and subdevices should request interrupts from us.

If not those handlers may find they are now running on suspended hardware despite holding a PM runtime reference. disable_irq() will sync any currently running handlers, so move the IRQ disabling to cover the whole of the forced suspend state to avoid such race conditions.

Quick overview of the entire LS2K BMC reset process: There are two types of reset methods: soft reset (BMC-initiated reboot of IPMI reset command) and BMC watchdog reset (watchdog timeout). First, regardless of the method, an interrupt is generated (PCIe interrupt for soft reset/GPIO interrupt for watchdog reset); Second, during the interrupt process, the system enters bmc_reset_work, clears the bus/IO/mem resources of the LS7A PCI-E bridge, waits for the BMC reset to begin, then restores the parent device's PCI configuration space, waits for the BMC reset to complete, and finally restores the BMC PCI configuration space. Display restoration occurs last.
