Subject: [PATCH] at91: set i2c_board_info.type to "ds1339" directly

The single element of the cpu9krea_i2c_devices array (of type struct
i2c_board_info) has its "type" member set twice. First to "rtc-ds1307"
(through the I2C_BOARD_INFO macro) and then directly to "ds1339". Just
set it (once and) directly to "ds1339" instead.

0) This is just something I stumbled upon while researching a different
issue. (An unrelated board apparently uses a ds1307 compatible RTC but
the kernel doesn't see it. I hope to submit a patch for that issue one
of these days.)

1) Entirely untested. I'm unsure what toolchain is needed to compile
this and I am certain that I don't have this hardware.

2) This is apparently legal. Doesn't gcc issue a warning for this?
