apalis_imx6: disable ri and dcd irq in uarts

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.
