defconfig: don't include support for hci_tty driver

Not required for Jellybean.
defconfig: enable SD card detection retries
panel: latona: restore pixel clock
latona: atmel: don't set any MXT_SPT_GPIOPWM value
drivers: max17040_battery: force RCOMP value

Taken from latona 2.6.35.
Without this patch the RCOMP value is set to d01e.
drivers: leds: latona: code cleanup and fixes

 * Let LEDs be turned off from the userspace
 * Turn both the LEDs on when softkeys are touched
 * Keep LEDs on while touching
panel: latona: set brightness to zero while turning on Hitachi panels

It was observed that Hitachi panels rarely set high brightness
values when they are turned on for a very short time.
Set the brightness to zero while they are powered on as it's done
for all the other panels to prevent this.
panel: latona: limit only Hitachi(17mA) panels

The changes were tested only on Hitachi(20mA). In old sources drop, where
Hitachi(17mA) panels are not mentioned, there are no limits.

Rework also the algorithm to limit the brightness to have a linear increase.
panel: latona: declare several functions as static
latona: properly remove the bus tput constraint
mach: opp: restore voltages
initramfs: don't create /emmc

It breaks the symlink for backward compatibility.
The directory is created whenever required.
latona: update C-state latencies and thresholds

Enable only the energy-wise interesting C-states.

block: Add support for reinsert a dispatched req

Add support for reinserting a dispatched request back to the
scheduler's internal data structures.
This capability is used by the device driver when it chooses to
interrupt the current request transmission and execute another (more
urgent) pending request. For example: interrupting long write in order
to handle pending read. The device driver re-inserts the
remaining write request back to the scheduler, to be rescheduled
for transmission later on.

Add API for verifying whether the current scheduler
supports reinserting requests mechanism. If reinsert mechanism isn't
supported by the scheduler, this code path will never be activated.

block: Add API for urgent request handling

This patch add support in block & elevator layers for handling
urgent requests. The decision if a request is urgent or not is taken
by the scheduler. Urgent request notification is passed to the underlying
block device driver (eMMC for example). Block device driver may decide to
interrupt the currently running low priority request to serve the new
urgent request. By doing so READ latency is greatly reduced in read&write
collision scenarios.

Note that if the current scheduler doesn't implement the urgent request
mechanism, this code path is never activated.
