tegra-sdhci: disable polling for hosts with non-removable cards
hosts with non-removable cards should not need to specify
MMC_CAP_POLLING; this causes additional exits from the CPU idle
loop.
add a field to the platform data to specify that the host is
removable, and initialize card_present to true if the host
is not removable
