drivers: mmc: Fix R2 response type definition
The Poplar is broken on eMMC initialization because of commit
2a82a9c95f6c ("drivers: emmc: dw_mmc: Add response flag into response ID
definition"). It changes the driver behavior on response type handling
in dw_send_cmd(), because MMC_RESPONSE_R(2) and MMC_RESPONSE_R2 are
different things. MMC core is still sending the former while we already
changed to check the latter in dw_mmc driver.
This patch fixes R2 response type in MMC core code. It's the same
thing as what commit 94522ff7f6d2 ("drivers: mmc: Fix R3 response type
definition") does for R3 response.
With this fix, Poplar is back to work.
