It doesn't seem right to me that in idle state, the UART has to keep the signal high against a pull-down resistor. This patch instead sets a 100k pull-up, which incidentally corresponds to the register reset value for all but one (MX53_PAD_KEY_ROW0__UART4_RXD_MUX) pad, and removes the write to the reserved bit.
