Add sysfs attribute to enable or disable cursor blinking. This will also
disable cursor blinking if the VT layer's softcursor is active. These changes
are required to enable some machines to enter low-power states properly.

The SCROLL_MOVE method has been optimized such that it is significantly faster
than SCROLL_REDRAW. Adjust flags to indicate that blitting is preferred over
rendering.

This patch replaces the current SCROLL_MOVE method with smarter method using
the same logic as the SCROLL_REDRAW method. This brings these two methods
much closer in performance and benefits all framebuffers which uses the
SCROLL_MOVE method.

Move brdp->iosize assignment in stli_initecp up a few lines to stop the
driver from requesting an I/O region of length 0.
Remove spin_lock_irqsave/spin_unlock_irqrestore from __stli_sendcmd as
all users of that function take the lock already.

Don't spin processor when not needed (use sleep instead of delay). Don't
release the lock when needed in next iteration -- this actually fixes a bug --

trident_write_voice_regs() was getting called with the card spinlock held in
only some cases. Fix it.
Explanation: we allocate a new virtual channel in open, and then we frob some
hardware registers (in write_voice_regs) for that channel. But the hardware
registers are shared with other channels, which may be trying to frob the some
registers (albeit for another channel) via ioctl(SNDCTL_DSP_SPEED).

When we find a ds1337 or ds1339 with the oscillator powered off, turn it
on. If the oscillator fault flag was set, clear it and warn that the clock
needs to be set.
David Brownell: Bugfixes; provide corresponding update for ds1338, and the
core of the fix for ds1340. Use a common warning message ("SET TIME!")
whenever the clock needs to be set after oscillator fault (or oscillator
enable, if fault is not a separate status).
