phy: ti: usb2: fix OMAP_CONTROL_PHY dependency

With randconfig build testing on arm64, we can run into a configuration
that has CONFIG_OMAP_CONTROL_PHY=m and CONFIG_OMAP_USB2=y, which in turn
causes a link failure:

drivers/phy/ti/phy-omap-usb2.o: In function `omap_usb_phy_power':
phy-omap-usb2.c:(.text+0x17c): undefined reference to `omap_control_phy_power'

I could not come up with a good way to correctly describe the relation
of the two symbols, but if we just select CONFIG_OMAP_CONTROL_PHY
during compile testing, we can no longer run into the broken configuration.

          Enable this to support the transceiver that is part of SOC. This
          driver takes care of all the PHY functionality apart from comparator.
