media: tc358746: select CONFIG_GENERIC_PHY
The tc358746 driver selects CONFIG_GENERIC_PHY_MIPI_DPHY and links to
that, but this fails when CONFIG_GENERIC_PHY is disabled, because Kbuild
then never enters the drivers/phy directory for building object files:
ERROR: modpost: "phy_mipi_dphy_get_default_config_for_hsclk" [drivers/media/i2c/tc358746.ko] undefined!
Add an explicit 'select GENERIC_PHY' here to ensure that the directory
is entered, and add another dependency on that symbol so make it
more obvious what is going on if another driver has the same problem,
as this will produce a Kconfig warning.
