[PATCH] rtc: Remove legacy DS1338 support

[PATCH] rtc: Remove legacy DS1338 support

[Tom Rini]

The DS1338 RTC chip is supported in DM mode by the DS1307 driver, and at
this point all users have been using this functionality. It was a
function of Kconfig configuration that implied otherwise. Remove the
unused legacy symbols.
