ARM: dts: qcom: ipq8064: add multiple missing pin definition

Add missing definition for mdio0 pins used for gpio-bitbang driver,i2c4
pins and rgmii2 pins for ipq8064.

Drop i2c4_pins node from ipq8064-ap148 dts as it's now moved to ipq8064
dtsi.

Drop mdio0_pins node from ipq8064-rb3011 dts as it's now moved to
ipq8064 dtsi.
