Konrad Dybcio 9bd9acd038 clk: qcom: reset: Ensure write completion on reset de/assertion 
[ Upstream commit 2f8cf2c3f3e3f7ef61bd19abb4b0bb797ad50aaf ]

Trying to toggle the resets in a rapid fashion can lead to the changes
not actually arriving at the clock controller block when we expect them
to. This was observed at least on SM8250.

Read back the value after regmap_update_bits to ensure write completion.
