ANDROID: PCI/PM: Use usleep_range for d3hot_delay

This patch implements a vendor hook that changes d3hot_delay to use
usleep_range() instead of msleep() to reduce the resume time from 20ms to 10ms.

The call sequence is as follows:
pci_pm_resume_noirq()
pci_pm_default_resume_early()
pci_power_up()
pci_raw_set_power_state() --> msleep(10)

The default d3hot_delay is 10ms. Using msleep for delays less than 20ms could
result in delays up to 20ms.
Reference: Documentation/timers/timers-howto.rst

Using usleep_range() results in the delay being closer to 10ms and this reduces
the resume time.
