Subject: [PATCH] rtc: isl12026: Add id_table

Add i2c id_table for isl12026 rtc.

Signed-off-by: Akhilesh Patil <akhilesh@...iitb.ac.in>
---
tested by instantiating isl12026 device as
echo "isl12026 0x6f" > new_device
Tested rtc on TI am62x sk board on i2c-2 using rtctest.
I am currently implementing alarm support for isl12026
this patch helps to instantiate device runtime without DT
for faster testing without reboots.
