mmc: sdhci-of-arasan: Increase CD stable timeout to 2 seconds

Browse Source 
On Xilinx/AMD platforms, the CD stable bit take slightly longer than
one second(about an additional 100ms) to assert after a host
controller reset. Although no functional failure observed with the
existing one second delay but to ensure reliable initialization, increase
the CD stable timeout to 2 seconds.
