mmc: sdhci-msm: factorise sdhci_msm_pdata outisde of sdhci_msm_host
There's no need to allocate one sdhci_msm_pdata for each sdhci_msm_host. This patch removes the sdhci_msm_pdata member from sdhci_msm_host and uses one static global sdhci_msm_pdata for all sdhci msm hosts. It also marks sdhci_msm_ops as const.
