mmc: cqhci: Increase HAC interrupt wait time in halt path

When system is heavily loaded, in some cases interrupt servicing
is getting effected and cmdq halt interrupt handler is getting invoked
after 1 sec delay. Since wait time of HAC interrupt in cmdq driver
is 1 sec, the delayed interrupt is being treated as unexpected
interrupt.
For fixing this case, increasing the timeout to 10 seconds.
