[U-Boot] [U-Boot, v2, 18/23] apalis_imx6: disable ri and dcd irq in uarts

[sbabic at denx.de]

> From: Max Krummenacher <max.krummenacher at toradex.com>
> If the UART is used in DTE mode the RI and DCD bits in UCR3 become
> irq enable bits. Both are set to enabled after reset and both likely
> are pending.
> Disable the bits also on UARTs not used in the boot loader to prevent
> an interrupt storm when Linux enables the UART interrupts.
