Subject: [PATCH 1/3] pinctrl: Ingenic: Fix bug and reformat the code.
1.Add tabs before values to align the code in the macro definition section.
2.Fix bugs related to the MAC of JZ4770, add missing pins to the MII group.
3.Adjust the sequence of X1830's SSI related codes to make it consistent
with other Ingenic SoCs.
4.Fix bug in "ingenic_pinconf_get()", so that it can read the configuration
of X1830 SoC correctly.
