Subject: [PATCH v5 4/5] Regulator: RK808: modify for struct rk808 change

The "dev" has been deleted from "struct rk808" in rk808 mfd driver
so rk808->dev should be replaced by &client->dev here.

Signed-off-by: Chris Zhong <zyw@...k-chips.com>

Changes in v5: None
Changes in v4:
Adviced by Lee Jones in v2
- modify the description in Kconfig
- remove some unnecessary header files
- remove dev from struct rk808
- use enum for define RK808_ID...

Changes in v3:
- fix compile err

Changes in v2:
Adviced by Mark Browm:
- use defines for register setting value
- remove rtc alarm disable in shutdown
- remove while(1) in shutdown
- remove read 0x2f in probe
