Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-bcm2835
to this allocation.

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.

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates the
sdhci-of-esdhc driver to this allocation.

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-tegra
to this allocation.

The sdhci_pltfm_init() function has initialized the priv member as
NULL, so there's no need to do it again.

Now all clients migration to use sdhci_pltfm_init for private
allocation is done and there's no users of the priv variable, so we can
remove it from the sdhci_pltfm_host structure.
