core/pci: Fix the power-off timeout in pci_slot_power_off()

The timeout should be 1000ms instead of 1000 ticks while powering
off PCI slot in pci_slot_power_off(). Otherwise, it's likely to
hit timeout powering off the PCI slot as below skiboot logs reveal:

[47912590456,5] SkiBoot skiboot-5.3.6 starting...
    :
[5399532365,7] PHB#0005:02:11.0 Bus 0f..ff  scanning...
[5399540804,7] PHB#0005:02:11.0 No card in slot
[5399576870,5] PHB#0005:02:11.0 Timeout powering off slot
[5401431782,3] FIRENZE-PCI: Wrong state 00000000 on slot 8000000002880005

This replaces time_wait() with time_wait_ms() to resolve the issue.
