clk: rockchip: add CLK_IGNORE_UNUSED flag to fix rk3066/rk3188 USB Host
This patch adds CLK_IGNORE_UNUSED flag to hclk_usb_peri, hclk_usbotg0 and hclk_usbotg1 because these clocks must remain enabled to use the USB controllers in host mode. This fixes a regression introduced by commit 78eaf6095cc7 ("clk: rockchip: disable unused clocks").
