mmc: Fixes block read prepare flow for eMMC

In order to start a multiple block read with pre-defined block count the
host must use the SET_BLOCK_COUNT command (CMD23) immediately preceding
the READ_MULTIPLE_BLOCK (CMD18) command. Otherwise the Device will start
an open-ended multiple block read that can be stopped using the
STOP_TRANSMISSION command.

So allow to excute mmc_send_ext_csd() several times in normal

In U-Boot, if change MMC device to hs400, it has to change to hs200

the mode firstly since the clock is higher than the hs ddr mode needed.
So change the clock firstly before change to hs ddr mode.

mmc: delete SEND_STATUS after set-timing in hs200 mode

In the eMMC spec, “Note that while the actual timing change is done,
the behavior of any command sent command sent (like CMD13) cannot be
guaranteed due to the asynchronous operation. Therefore it is not
recommended to use CMD13 to check the busy completion of the timing
change indication.” indicates that SEND_STATUS can not be send after
set-timing, so delete it.
