This is a useful information while debugging the initialization process or performance issues. Also dump this information with the other mmc info if the verbose option is selected
Signed-off-by: Jean-Jacques Hiblot jjhiblot@ti.com --- changes since v2: * dump the capabilities during the initialization only when debug is enabled * dump teh capabilities in print_mmcinfo() if the MMC_VERBOSE option is enabled (it's enabled by default).
