Original operation_mode sysfs attribute accepts the operation mode
as main value with an option delay as second value to change
the start-up delay on mode change.

As it is preferred to have exactly one value per sysfs attribute,
extract this delay into a separate sysfs attribute called
operation_mode_delay.

HID_PICOLCD should depend on LCD_CLASS_DEVICE, otherwise the
build fails when HID_PICOLCD=y and LCD_CLASS_DEVICE=m:

hid-picolcd.c:(.text+0x84523f): undefined reference to `lcd_device_unregister'
hid-picolcd.c:(.text+0x8478ab): undefined reference to `lcd_device_register'
hid-picolcd.c:(.text+0x84c15f): undefined reference to `lcd_device_unregister'

Same applies to FB, BACKLIGHT_CLASS_DEVICE and LEDS_CLASS.

Add suboptions for those features to handle the deps on kbuild side
and just check HID_PICOLCD_* in the code.

Some BIOSes don't configure HPA during boot but do so while resuming.
This causes harddrives to shrink during resume making libata detach
and reattach them.  This can be worked around by unlocking HPA if old
size equals native size.

Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled
per-device and update ata_dev_revalidate() such that it sets
ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is
detected.

This patch fixes the following bug.

Crucial said,

  Thank you for contacting us. We know that with our M225 line of SSDs
  you sometimes need to disable NCQ (native command queuing) to avoid
  just the type of errors you're seeing. Our recommendation for the
  M225 is to add libata.force=noncq to your Linux kernel boot options,
  under the kernel ATA library option.

  I have sent your feedback to the engineers working on the C300, and
  asked them to please pass it on to the firmware team. I have been
  notified that they are in the process of testing and finalizing a
  new firmware version, that you can expect to see released around the
  end of April. We’ll keep you posted as to when it will be available
  for download.

So, turn off NCQ on the drive w/ the current firmware revision.

bond_uninit() is invoked with rtnl_lock held, when it does destroy_workqueue()
which will potentially flush all works in this workqueue, if we hold rtnl_lock
again in the work function, it will deadlock.

So move destroy_workqueue() to destructor where rtnl_lock is not held any more,
suggested by Eric.
