Arvind Yadav 45a6351849 rtc: constify i2c_device_id
i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Peter Robinson e706974dc3 drivers/rtc/rtc-em3027.c: add device tree support
Set the of_match_table for this driver so that devices can be described in
the device tree.  This device is used in the Trimslice and is already
defined in the Trimslice device tree.

Sachin Kamat 2a7a145e78 drivers/rtc/rtc-em3027.c: remove empty function
After the switch to devm_* functions and the removal of
rtc_device_unregister(), the 'remove' function does not do anything.
Delete it.

Jingoo Han 019b21d07a rtc: rtc-em3027: use devm_rtc_device_register()
devm_rtc_device_register() is device managed and makes cleanup paths
simpler.

Shubhrajyoti D 84cab86cb8 drivers/rtc/rtc-em3027.c: convert struct i2c_msg initialization to C99 format
Convert the struct i2c_msg initialization to C99 format.  This makes
maintaining and editing the code simpler.  Also helps once other fields
like transferred are added in future.

Paul Gortmaker 2113852b23 rtc: Add module.h to implicit users in drivers/rtc
The module.h was implicitly everywhere, but when we clean
that up, the implicit users will compile fail; fix them up
in advance.
