Jaehoon Chung 2378975bd5 mmc: core: warn when card doesn't support HPI
Someone could use send_hpi_cmd() on a card that doesn't advertise support
for HPI.  Then maybe didn't work fine.  Because card->ext_csd.hpi_cmd
didn't set.  So if card didn't support hpi, return the warning message.

And CMD12's flags is MMC_RSP_R1B.
