ARM: dts: dra7-clock: Add "l3init_960m_gfclk" clock gate
This clock gate description is missing in the older Reference manuals.
It is present on the SoC to provide 960MHz reference clock to the
internal USB PHYs.
Reference: DRA75x_DRA74x_ES1.1_NDA_TRM_vO.pdf, pg. 900,
Table 3-812. CM_COREAON_L3INIT_60M_GFCLK_CLKCTRL
Use l3init_960m_gfclk as parent of usb_otg_ss1_refclk960m and
usb_otg_ss2_refclk960m.
