Jan Kaisrlik 8ad8e02c2f Revert "mmc: core: do not retry CMD6 in __mmc_switch()"
Turns out the commit 3a0681c744 ("mmc: core: do not retry CMD6 in
__mmc_switch()") breaks initialization of a Toshiba THGBMNG5 eMMC card,
when using the meson-gx-mmc.c driver on a custom board based on Amlogic
A113D.

The CMD6 that switches the card into HS200 mode is then one that fails and
according to the below printed messages from the log:

[    1.648951] mmc0: mmc_select_hs200 failed, error -84
[    1.648988] mmc0: error -84 whilst initialising MMC card

After some analyze, it turns out that adding a delay of ~5ms inside
mmc_select_bus_width() but after mmc_compare_ext_csds() has been executed,
also fixes the problem. Adding yet some more debug code, trying to figure
out if potentially the card could be in a busy state, both by using CMD13
and ->card_busy() ops concluded that this was not the case.

Therefore, let's simply revert the commit that dropped support for retrying
of CMD6, as this also fixes the problem.
