mmc: sdhci-msm: Enable delay circuit calibration clocks

The delay circuit used to support HS400 is calibrated based on two
additional clocks. When these clocks are not available and
FF_CLK_SW_RST_DIS is not set in CORE_HC_MODE, reset might fail. But on
some platforms this doesn't work properly and below dump can be seen in
the kernel log.

  mmc0: Reset 0x1 never completed.

Add support for the additional calibration clocks to allow these
platforms to be configured appropriately.
