ARM: dts: dra7-clock: Add "l3init_960m_gfclk" clock gate

Browse source 
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.
