net: phy: dp83869: fix setting CLK_O_SEL field.

Browse source

[ Upstream commit 46f74a3f7d ]

Table 7-121 in datasheet says we have to set register 0xc6
to value 0x10 before CLK_O_SEL can be modified. No more infos
about this field found in datasheet. With this fix, setting
of CLK_O_SEL field in IO_MUX_CFG register worked through dts
property "ti,clk-output-sel" on a DP83869HMRGZR.
