ENGR00155138 mx53_smd/mx53_loco: Add i2c retry to fix DA9053 i2c NAK issue
when board boots up, during the iMX53 SOC does DA9053 Read/Write
operation, it writes slave address and wait for ACK . Instead of ACK
PMIC sends NAK. A workaround fix is provided as a part of retries to
fix I2C NAK for very first access.
