meson_saradc's irq handler uses priv->regmap so make sure that it is allocated before the irq get enabled. This also fixes crash when CONFIG_DEBUG_SHIRQ is enabled, as device managed resources are freed in the inverted order they had been allocated, priv->regmap was freed before the spurious fake irq that CONFIG_DEBUG_SHIRQ adds called the handler.
