It's not necessary as it's already defined in ar934x.dtsi to:
pll-data = <0x16000000 0x00000101 0x00001616>;
And in ar71xx it's currently set to the same values:
#define AR934X_PLL_VAL_1000 0x16000000
#define AR934X_PLL_VAL_100 0x00000101
#define AR934X_PLL_VAL_10 0x00001616
And dumping the value from the airOS v6.1.7 has the same value:
AR934X_PLL_ETH_XMII_CONTROL_REG 0x1805002C 0x101
