xhci: Increase STS_HALT timeout in xhci_suspend()
I've recently observed failed xHCI suspend attempt on AMD Raven Ridge
system:
kernel: xhci_hcd 0000:04:00.4: WARN: xHC CMD_RUN timeout
kernel: PM: suspend_common(): xhci_pci_suspend+0x0/0xd0 returns -110
kernel: PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110
kernel: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -110
kernel: PM: Device 0000:04:00.4 failed to suspend async: error -110
Similar to commit ac343366846a ("xhci: Increase STS_SAVE timeout in
xhci_suspend()") we also need to increase the HALT timeout to make it be
able to suspend again.
