ti: dwc3: Enable clocks in enable_basic_clocks() in hw_data.c 

Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY)
changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl
to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl
to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between
the two dwc3 controllers present in dra7xx/am43xx and enabled these
clocks in enable_basic_clocks() in hw_data.c. However these clocks
continued to be enabled in board files/driver files for dwc3 host
mode functionality causing compilation break with few configs.

Fixed it here by making all the clocks enabled in enable_basic_clocks()
and removing it from board files/driver files here.
