From: Frank Li <Frank.Li@nxp.com>

commit 808e7716edcdb39d3498b9f567ef6017858b49aa upstream.

usb2_lpcg: clock-controller@5b270000 {
... Col1 Col2
clocks = <&conn_ahb_clk>, <&conn_ipg_clk>; // 0 6
clock-indices = <IMX_LPCG_CLK_6>, <IMX_LPCG_CLK_7>; // 0 7
...
};

Col1: index, which existing dts try to get.
Col2: actual index in lpcg driver.

usbotg1: usb@5b0d0000 {
...
clocks = <&usb2_lpcg 0>;
^^
Should be:
clocks = <&usb2_lpcg IMX_LPCG_CLK_6>;
};

usbphy1: usbphy@5b100000 {
clocks = <&usb2_lpcg 1>;
^^
SHould be:
clocks = <&usb2_lpcg IMX_LPCG_CLK_7>;
};

Arg0 is divided by 4 in lpcg driver. So lpcg will do dummy enable. Fix it
by use correct clock indices.
