Timed output vibrator: New functionality.

This patch allows to form the vibration characteristic
using few parameters defined in the platform data:
- boost level and period for start condition
- on level as moderate speed
- off level and period for brake condition

vibrator: remove board specific control of vibrator

Platform specific control of vibrator should be
present in board file (here board-mop500.c).

So, for example if GPIO pins are used to control
the vibrator, its control function implemenation
should be in board file.

This patch provides the callback function support
in the driver for the same.

Use ktime helper functions for converting ktime values

u8500: vibra: linear vibrators using vibra-pwm

Linear vibrators operate on thier required resonance
frequency (for COPAL and AAC its ~150Hz). This can be
provided using AUDIO DA5 path. This software *workaround*
enables linear vibrators using AB8500 vibra-pwm by
generating required resonace frequency using software.

In addition this patch provides support for separate
platform data for Linear and Rotarty vibrators.

u8500: vibra: disable vibrator after vibration

This patch disables vibrator i.e. configures
the PWM duty cycle to zero after vibration
duration is over.
