[PATCH v3] clk: qcom: reset: Use the correct type of sleep/delay based on length

[PATCH v3] clk: qcom: reset: Use the correct type of sleep/delay based on length

[Konrad Dybcio]

Use the fsleep() helper that (based on the length of the delay, see: [1])
chooses the correct sleep/delay functions.

Fixes: 2cb8a39b6781 ("clk: qcom: reset: Allow specifying custom reset delay")

Let the toggle include a bigger delay and make sure it's using the
correct function to achieve that.

- Improve the commit message
- Link to v2: https://lore.kernel.org/r/20230726-topic-qcom_reset-v2-1-4a6e1b1d0439@linaro.org

Changes in v2:
- Drop the "allow bigger delay" until there's a user
- Use fsleep instead of open-coding effectively the same
- Fix the fixes tag
- Link to v1: https://lore.kernel.org/r/20230726-topic-qcom_reset-v1-0-92de6d3e4c7c@linaro.org
