Subject: [RFC v2 2/2] mmc: host: omap_hsmmc: revert special init for wl1251

Replaces: commit f6498b922e57 ("mmc: host: omap_hsmmc: add code for special init of wl1251 to get rid of pandora_wl1251_init_card")
Requires: commit ("mmc: core: transplant ti,wl1251 quirks from omap_hsmmc")

After moving the wl1251 quirks from omap_hsmmc_init_card() to mmc_fixup_device()
we can remove omap_hsmmc_init_card() which specialized on the combination of
omap_hsmmc and wl1251.

Related-to: commit f6498b922e57 ("mmc: host: omap_hsmmc: add code for special init of wl1251 to get rid of pandora_wl1251_init_card")
Related-to: commit 2398c41d6432 ("omap: pdata-quirks: remove openpandora quirks for mmc3 and wl1251")
Related-to: commit f9d50fef4b64 ("ARM: OMAP2+: omap3-pandora: add wifi support")
