[PATCH V2 1/9] mfd: 88pm800: fix NULL pointer error

[Chao Xie <chao.xie@marvell.com>]

From: Yi Zhang <yizhang@marvell.com>

move "device_800_init" to fix NULL pointer error when
calling "device_gpadc_init"

for "device_gpadc_init" needs "subchip->regmap_gpadc"
to set registers via regmap interface
