[U-Boot-Users] [PATCH] I2C register access functions for omap1510_i2c driver

[Ladislav Michl]

drivers/i2c/omap1510_i2c.c does not implement i2c_reg_read and
i2c_reg_write which leads to unresolved symbols when using ds1307
driver. While there, enable CONFIG_CMD_DATE for Voiceblue board to have
nice test case :-)
