Let's convert the lpass clock control driver to use devm.  This is a
few more lines of code, but it will be useful in a later patch which
disentangles the two devices handled by this driver.

(no changes since v4)

Changes in v4:
- Fixed typo lapss => lpass
- Moved lpass_pm_runtime_disable() lpass_pm_clk_destroy() in file.

Changes in v3:
- ("clk: qcom: lpasscc-sc7810: Use devm in probe") new for v3.

This pattern is common. We should consider pulling this into qcom/core.c
and consolidating code a bit.
