pinctrl: Ingenic: Fix bugs in X1000 and X1500.

1.Fix the pullup parameter of X1000.
2.X1000 and X1500 have only one set of uart1 hwflow pin mapping,
  so modify "uart1_hwflow_d" to "uart1_hwflow".
3.X1000 has only one set of mmc1 pin mapping, so modify
  "mmc1-1bit-e/mmc1-4bit-e" to "mmc1-1bit/mmc1-4bit".
4.X1000 has only one regular externel memory controller that
  does not support nand flash, so change "nemc_" to "emc_".
5.X1500 has only one set of mmc, so modify "mmc0_" to "mmc_".
