i.MX: clk-pllv3: Initially disable PLL_BYPASS bit
Commit cbff8031b491 ("i.MX: clk-pllv3: Do not touch PLL_BYPASS bit")
overreached a bit by removing the code that disables the PLL_BYPASS bit
for all architectures instead of making an exception for Vybrid and
i.MX6SL. This causes the USB controller on i.MX6Q to run at bypass
frequency and fail:
barebox@Boundary Devices i.MX6 Quad Nitrogen6x Board:/ usb
usb: USB: scanning bus for devices...
usb: Bus 001 Device 001: ID 0000:0000 EHCI Host Controller
imx-usb 2184200.usb: port(0) reset error
This patch adds code to unconditionally disable the PLL_BYPASS bit
initially, when the PLL clocks are registered.
