Add support for Maxim's DS4510 I2C device Initial support for the DS4510, a CPU supervisor with integrated EEPROM, SRAM, and 4 programmable non-volatile GPIO pins. The CONFIG_DS4510 define enables support for the device while the CONFIG_CMD_DS4510 define enables the ds4510 command. The additional CONFIG_DS4510_INFO, CONFIG_DS4510_MEM, and CONFIG_DS4510_RST defines add additional sub-commands to the ds4510 command when defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
