[PATCH 2/3] mmc: zynq_sdhci: Change granularity of timeout to 1us

[Michal Simek]

From: Ashok Reddy Soma <ashok.reddy.s...@xilinx.com>

The timeout used in 'commit b6f44082d5cd ("mmc: zynq_sdhci: Wait
till sd card detect state is stable")' workaround is 1000ms at a
granularity of 1msec. Change it to 1usec, to not waste time incase the
cd is stable.
