Subject: [PATCH] mmc: omap_hsmmc: fix timeout for cmd and data soft reset

With HSMMC_HAS_UPDATED_RESET reset of cmd/data (SRC/SRD) can be to
quick and can be missed resulting in wait for software timeout.
With cpu_relax timeout can be long and unpredictable. Use udelay
instead for timeout implementation.
