Marcin Bukat 0dc08e53a9 S-35390A RTC: bring the driver back, handle 12-hour mode 
The S-35390A keeps the hour either as 0-23 or - its default after a
power-on reset - as 0-11 plus a p.m. flag, selected by the 12/24 bit of
status register 1. The driver assumed 24-hour mode and never set it: it
masked the p.m. flag off, so on a chip left in 12-hour mode every
afternoon read as morning, and writing an afternoon time stored an
out-of-range hour.

Read the mode in rtc_init() and convert the hour both ways. The chip's
mode is left alone, as another firmware on the same player may depend on
it - the Samsung YP-CP3's original firmware runs it in 12-hour mode and
never touches the bit. If the status register cannot be read, the driver
keeps assuming 24-hour mode, as before.

Upstream removed the driver with its only users, the Meizu M3/M6 and
Samsung YP-S3 ports (1a33d7990a); the Samsung YP-CP3 needs it, so it
comes back here, with RTC_S35390A and its SOURCES entry.

Also pick the I2C header by CONFIG_I2C, so rk27xx targets can use the
driver; i2c_read()/i2c_write() have the same shape there.
