dpll: zl3073x: ZL3073X_I2C and ZL3073X_SPI should depend on NET

When making ZL3073X invisible, it was overlooked that ZL3073X depends on
NET, while ZL3073X_I2C and ZL3073X_SPI do not, causing:

    WARNING: unmet direct dependencies detected for ZL3073X when selected by ZL3073X_I2C
    WARNING: unmet direct dependencies detected for ZL3073X when selected by ZL3073X_SPI
    WARNING: unmet direct dependencies detected for ZL3073X
	Depends on [n]: NET [=n]
	Selected by [y]:
	- ZL3073X_I2C [=y] && I2C [=y]
	Selected by [y]:
	- ZL3073X_SPI [=y] && SPI [=y]

Fix this by adding the missing dependencies to ZL3073X_I2C and
ZL3073X_SPI.
