add OMAP3630 sd/mmc1 speed mode config for prog_io1 in mmc1_init pinctrl state

Looks OK to me, except these should be under mmc1 for omap[345].dtsi files.


I think I can move &omap3_pmx_general to omap3.dtsi and override
&pbias_1v8, &pbias_3v in omap36xx.dtsi, but I doubt pinctrl-[0,1,2,3,4]
since pull up setting can vary between boards.

Tony
