[PATCH v2 02/16] rtc: s5m: drop needless struct s5m_rtc_info::i2c member

[André Draszik]

When this driver was converted to using the devres managed i2c device
in commit 7db7ad0817fe ("rtc: s5m: use devm_i2c_new_dummy_device()"),
struct s5m_rtc_info::i2c became essentially unused.

We can drop it from the structure and just use a local temporary
variable, reducing runtime memory consumption by a few bytes.

v2:
* fix arguments to devm_i2c_new_dummy_device() - too eager sed //, and
  gcc didn't notice, only clang :-(
