[PATCH] ARM: versatile: enable RTC DS1338 driver in defconfig

[Milo Kim]

Versatile platform boards[*] support external RTC device, DS1338.
It is compatible with rtc-ds1307 device driver.
This driver requires not only RTC subsystem configuration but also I2C host
bus support.

QEMU[**] also supports this device by default.
