Update pinmux to get rid of invalid uses of the rsvd1 function and add correct drive settings for SDIO1, which makes some more SD-cards work.
(Adding a variety of missing CCs) I think this patch looks OK. Looking at the kernel pinctrl driver, I think that before this patch, because some of the mux settings were deemed invalid by the pinctrl driver, the pinmux settings were not all applied, and this change fixes it? Ouch! Luckily U-Boot programmed what is hopefully the same table before the kernel booted!
