Some mmc operations take longer than maximum HW busy detection and
mmc core driver converts R1B type to R1 type response for these
operations based on host max busy timeout and command operation time
and uses SW poll for busy.

Tegra host support long HW busy detection where host waits forever
till the card is busy.

This patch enables MMC_CAP2_LONG_WAIT_HW_BUSY capability for Tegra
host.
