[RESEND PATCH v2] clk: imx: scu: Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage

[Miaoqian Lin]

If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1.

Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync()
fails, so use pm_runtime_resume_and_get() instead. this function
will handle this.

Fixes: 78edeb080330 ("clk: imx: scu: add runtime pm support")

changes in v2:
- change pm_runtime_get_sync to pm_runtime_resume_and_get
- current check works fine for pm_runtime_resume_and_get() so stay the
same.
