mmc: sdhci-f-sdh30: Replace with sdhci_pltfm

Even if sdhci_pltfm_pmops is specified for PM, this driver doesn't apply
sdhci_pltfm, so the structure is not correctly referenced in PM functions.
This applies sdhci_pltfm to this driver to fix this issue.

- Call sdhci_pltfm_init() instead of sdhci_alloc_host() and
  other functions that covered by sdhci_pltfm.
- Move ops and quirks to sdhci_pltfm_data
- Replace sdhci_priv() with own private function sdhci_f_sdh30_priv().

Fixes: 87a507459f ("mmc: sdhci: host: add new f_sdh30")
