Subject: clk: bcm: rpi: Make sure pllb_arm is removed
Git-commit: 683de1868164ec8d252ec9261a5dfd0f9edd7f52
Patch-mainline: v5.9-rc1
References: jsc#SLE-15318

The pllb_arm clock was created at probe time, but was never removed if
something went wrong later in probe, or if the driver was ever removed from
the system.

Now that we are using clk_hw_register(), we can just use its managed variant
to take care of that for us.
