iio: adc: meson_saradc: Fix memory allocation order
[ Upstream commit de10ac47597e7a3596b27631d0d5ce5f48d2c099 ]
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.
Fixes: 3af109131b7eb8 ("iio: adc: meson-saradc: switch from polling to interrupt mode")
