[RFT v2 04/10] pinctrl: samsung: Add dedicated compatible for S5Pv210 wakeup interrupts

The S5Pv210 external wakeup interrupts differ from Exynos therefore
separate compatible is needed. Duplicate existing flavor specific data
from exynos4210_wkup_irq_chip and add new compatible for S5Pv210.
At this point this new compatible does not bring anything new and works
exactly as existing "samsung,exynos4210-wakeup-eint".
