Michael (XIAO Xufeng) 55bb42dc63 sdmmc: fix the probe issue that forbid sdspi working in highspeed mode
SD cards don't support CMD7 (select_card) in SPI mode. Highspeed probe
of sdspi will fail in this step and stop working in highspeed mode.
Remove the CMD7 in enable_hs_mode_and_check to fix this issue.

Please note that, on ESP32, you have to use the IOMUX pins to use sdspi
in 40MHz, otherwise the initialization process will report reading issue
and fail.
