03dcc544bf mfd: 88pm80x: Change chip id definition and detection
Change the chip id definition and detection and then:

1. We no longer need to add PM800_CHIP_XXX for the coming revision.
2. We no longer need to pass driver_data in i2c_device_id as we
   can distinguish the chips from the CHIP_ID register.

706c96b720 mfd: Remove __devexit annotation for pm80x_deinit
This fixes below section mismatch warning:

  LD      drivers/mfd/built-in.o
WARNING: drivers/mfd/built-in.o(.devinit.text+0x46c): Section mismatch in reference from the function pm800_probe() to the function .devexit.text:pm80x_deinit()
The function __devinit pm800_probe() references
a function __devexit pm80x_deinit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
pm80x_deinit() so it may be used outside an exit section.

5500e3964b mfd: Add companion chip in 88pm80x
in hw design, 800 is mainly for pmic control, while 805 for audio.
but there are 3 registers which controls class D speaker property,
and they are defined in 800 i2c client domain. so 805 codec driver
needs to use 800 i2c client to access class D speaker reg for
audio path management. so add this workaround for the purpose to
let 805 access 800 i2c in some scenario.

70c6cce040 mfd: Support 88pm80x in 80x driver
88PM800 and 88PM805 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according
to requirement.

88pm80x.c provides common i2c driver handling for both 800 and
805, such as i2c_driver init, regmap init, read/write api etc.

88pm800.c handles specifically for 800, such as chip init, irq
init/handle, mfd device register, including rtc, onkey, regulator(
to be add later) etc. besides that, 800 has three i2c device, one
regular i2c client, two other i2c dummy for gpadc and power purpose.

88pm805.c handles specifically for 805, such as chip init, irq
init/handle, mfd device register, including codec, headset/mic detect
etc.

the i2c operation of both 800 and 805 are via regmap, and 88pm80x-i2c
exported a group of r/w bulk r/w and bits set API for facility.
