This series is to backport the upstream patches that fixes busy

for long operation mmc commands by implementing Tegra specific timeout

Sowjanya Komatineni (2):
sdhci: tegra: Implement Tegra specific set_timeout callback
sdhci: tegra: Enable MMC_CAP_WAIT_WHILE_BUSY host capability
What regression do these patches fix?
This isn't a regression as we don't have any known failures as of today
with the specific mmc devices we are using on our platforms.
But this patch fixes a long outstanding bug for sdhci-tegra to handle
long busy wait for mmc command operations that may take longer than host
max busy timeout. So, this is something that's missing from the
beginning and good to have.
