Robert Beckett 1dec7fa797 board: ge: bx50v3, imx53ppd: use DM I2C
Remove old (pre-DM) i2c setup code.
Enable DM i2c.
Convert common code to use DM rtc.
Convert common code to read VPD from eeprom partition.
Convert the generic i2c PMIC init code to use the new da9063 driver.

mx53ppd only:
Correct RTC compatible in device tree.
Enable MXC DM i2c driver.
Define CONFIG_SYS_MALLOC_F_LEN so that DM is available in pre-reloc.
Make GPIO banks available during preloc, since initialisation is done
in board_early_init_f().
Add gpio_request() calls to satisfy the DM_GPIO compatibility API.
Remove unused power configuration.
