Two separate de-init functions are merged into one common function.
And it is used in err_post_init of lp55xx_init_device().

lp5521/5523_init_device() are replaced with lp55xx common function,
lp55xx_init_device().
Error handler in init_device:
deinit function are matched with 'err_post_init' section in
lp55xx_init_device().
Remove LP5523 engine intialization code:
Engine functionality is not mandatory but optional.
Moreover engine initialization is done internally with device reset command.
Therefore, this code is unnecessary.

LP5521/5523 chip configuration is replaced with lp55xx common function,
lp55xx_post_init_device().
Name change:
lp5521/5523_configure() to lp5521/5523_post_init_device()
These are called in init function.
Register access function
Argument type is changed from 'i2c_client' to 'lp55xx_chip'.
Use exported R/W functions of lp55xx common driver.
Temporary variables in lp5521/5523_init_device()
These functions will be removed but temporary variables are needed for
blocking build warnings - incompatible pointer.

LP5521/5523 chip detection functions are replaced with lp55xx common function,
lp55xx_detect_device().
Chip dependent address and values are configurable in each driver.
In init function, chip detection is executed.

LP5521/5523 reset device functions are moved to lp55xx common driver.
Value of register address and value are chip dependent.
Those are configured in each driver.
In init function, reset command is executed.

This patch supports basic common driver code for LP5521, LP5523/55231 devices.
( Driver Structure Data )
lp55xx_led and lp55xx_chip
In lp55xx common driver, two different data structure is used.
o lp55xx_led
control multi output LED channels such as led current, channel index.
o lp55xx_chip
general chip control such like the I2C and platform data.
For example, LP5521 has maximum 3 LED channels.
LP5523/55231 has 9 output channels.
lp55xx_chip for LP5521 ... lp55xx_led #1
lp55xx_led #2
lp55xx_led #3
lp55xx_chip for LP5523 ... lp55xx_led #1
lp55xx_led #2
.
.
lp55xx_led #9
( Platform Data )
LP5521 and LP5523/55231 have own specific platform data.
However, this data can be handled with just one platform data structure.
The lp55xx platform data is declared in the header.
This structure is derived from leds-lp5521.h and leds-lp5523.h
