[PATCH v4 16/23] ARM: OMAP2+: clock data: Merge utmi_px_gfclk into usb_host_hs_utmi_px_clk

There is no such clock as utmi_p1_gfclk. It is only a clock selector
bit to select th the parent of usb_host_hs_utmi_p1_clk.
So we get rid of utmi_p1_gfclk and utmi_p2_gfclk by merging them into
usb_host_hs_utmi_p1_clk and usb_host_hs_utmi_p2_clk respectively.
