pinctrl: qcom: Fix msm_dirconn_uncfg_reg() to correctly set intr cfg

msm_dirconn_uncfg_reg() currently uses readl_/writel_relaxed() which do not
check for per tile address for gpio intr cfg. Replace to use
msm_readl/writel_intr_cfg() which takes care of per tile.

While at this also fix dir_conn_reg to use per tile gpio cfg.
