Since we want to keep support for both older usb-phys as well as the
newer generic phys, lets first get the generic PHYs and fallback to
older USB-PHYs only when we fail to get the former.
This should fix the issue with ehci-exynos and ohci-exynos, wherein
in the absence of SAMSUNG_USB2PHY config symbol, we end up getting
the NOP_USB_XCEIV phy when the same is enabled. And thus the PHYs
are not configured properly.

Fujitsu backlight and hotkey devices have ACPI drivers.
The PNP MODULE_DEVICE_TABLE in fujitsu-laptop driver is just used as an
indicator for module autoloading, but this is wrong because what we
need is ACPI module device table instead, because the driver is probing
ACPI devices.
Thus remove those IDs from ACPI PNP scan handler list as we don't
have a PNP driver for them, and convert the fujitsu-laptop PNP
MODULE_DEVICE_TABLE to ACPI MODULE_DEVICE_TABLE.

It is impossible to tell the difference from the evdev info without

undesirable.
