mmc: sdhci-pltfm: Fix linking err for sdhci-brcmstb
commit d7fb9c24209556478e65211d7a1f056f2d43cceb upstream.
The implementation of sdhci_pltfm_suspend() is only available when
CONFIG_PM_SLEEP is set, which triggers a linking error:
"undefined symbol: sdhci_pltfm_suspend" when building sdhci-brcmstb.c.
Fix this by implementing the missing stubs when CONFIG_PM_SLEEP is unset.
