Shawn Lin e61fd89e2f BACKPORT: FROMLIST: mmc: core: Don't try UHS-I mode if 4-bit mode isn't supported 
Per SD specification physical layer v4.0, section 3.9.4, it
says "UHS-I supports only 4-bit mode. Host shall select 4-bit
mode by ACMD6. However mmc_sd_init_uhs_card() still go ahead
to initialize the cards anyway, whether card or host won't
support 4-bit mode.

This breaks the platforms which only support 1-bit mode but
with a UHS-I card inserted, as all the tuning process is broken
due to this. Alternatively, we should check the return value from
mmc_set_bus_width to see if host could finish the request to switch
the bus with on its side. But that needs more thing to do than this
patch that just bails out early to try to use high speed mode if 4-bit
mode isn't available for whatever reason. And this patch could also
fix the same problem for sdio since R4_18V_PRESENT won't be set for
ocr when mmc_sdio_init_card() finds mmc_host_uhs() is false.

Note that This patch doesn't keep the checking of card->scr.sda_spec3
and comparing card->scr.bus_widths with SD_SCR_BUS_WIDTH_4 within
mmc_sd_init_uhs_card since if the sd cards response with SD_ROCR_S18A,
it definitely support UHS-I mode, which implicitly means these checks
are always true.
