Subject[RESEND PATCHv1 5/8] mmc: sdhci-msm: configure CORE_CSR_CDC_DELAY_CFG to recommended value
Message-ID<sXYJb-6JW-3@gated-at.bofh.it>
From: Subhash Jadavani <subhashj@codeaurora.org>

Program CORE_CSR_CDC_DELAY_CFG for hardware recommended 1.25ns delay.
We may see data CRC errors if it's programmed for any other delay
value.
