To make RTC block of MAX77686/MAX77802 as independent driver,
move the registration of i2c device, regmap for register access
and irq_chip for interrupt support inside the RTC driver.
Removed the same initialisation from MFD driver.

Having this change will allow to reuse this driver for different
PMIC/devices from Maxim Semiconductor if they kept same RTC IP on
different PMIC. Some of examples as PMIC MAX77620, MAX20024 where
same RTC IP used and hence driver for these chips will use this
driver only for RTC support.

Changes from V1:
- Remove changes from Kconfig.
- Maintain all register definition in max77686 private header and remove
  the movement to rtc driver.
- Taken care of all comments on V1 from Krzysztof and Javier.

Changes from V2:
- Taken care of missed sequence for removing the resource.
- Fix the crash when doing unbind by using requested_threaded_irq()
  instead of demv_requested_threaded_irq().

Changes from V3:
- Fix the issue of suspend-resume with unbind/bind by unmapping the
  virq.

Changes from V4:
- Dispose mapped irq in error path in probe

Changes from V5:
- Remove the new APIs from regmap as functionality added to dispose the
  virq inside the regmap_del_irq_chip().

Changes from V6:
Make this as 5th of series as regmap change applied independently.
Also rebase on linux-next 20160209
