Add support for Epson rx8571 real-time clock. rx8571 rtc is compatible
with rx8581,except that rx8571 has additional 16 bytes of RAM.
16 bytes of nvmem is supported and exposed in sysfs (# is the instance
number,starting with 0): /sys/bus/nvmem/devices/rx8571-#/nvmem

rtc: rx8581: Add OF device ID table2017-03-09T00:29:31ZJavier Martinez Canillasjavier@osg.samsung.com2017-03-03T14:29:22Zurn:sha1:ffbecfbdbeeebe9749398fe9eb9eab2dd47ddff4
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
