mmc: sdhci-msm: Affine irq to first set of mask when CONFIG_SMP enabled

Browse source 
For MDM targets with single CPU, CONFIG_SMP won't be enabled so
irq_set_affinity_hint will always return EINVAL leading to unnecessary
WARN_ON.

Use irq_set_affinity_hint only for multiple CPU's or when CONFIG_SMP
enabled.
