MLK-10449-1: 74x164: Add new property registers-default
For some platform such as imx7D SDB, one pin of 74x164 to
control all peripheral power supply(PERI_3V_EN).
The pin should keep in high voltage level when 74x164 loading,
otherwise the module depend on PERI_3V3 will lose power.
So add new property registers-default into 74x164 driver.
