mx6memcal: Fix the UART ports for mx6sabresd/auto boards

mx6sabresd board uses the following pins for console:

PAD_CSI0_DAT10__UART1_TX_DATA
PAD_CSI0_DAT11__UART1_RX_DATA

,so put it in the same config option as wandboard.

mx6sabreauto board uses the following pins for console:

PAD_KEY_COL0__UART4_TX_DATA
PAD_KEY_ROW0__UART4_RX_DATA

So do not mention sabreauto board as part of the UART1_SD3_DAT6_7 option.

The config option for sabreauto can be added later when needed.
