mmc: t210: Add autocal and tap/trim updates for SDMMC1/3
As per the T210 TRM, when running at 3.3v, the SDMMC1 tap/trim and
autocal values need to be set to condition the signals correctly before
talking to the SD-card. This is the same as what's being done in CBoot,
but it gets reset when the SDMMC1 HW is soft-reset during SD driver
init, so needs to be repeated here. Also set autocal and tap/trim for
SDMMC3, although no T210 boards use it for SD-card at this time.
