[PATCH v3 25/31] clk: mediatek: pll: Implement error handling in register API

[Stephen Boyd]

Quoting Chen-Yu Tsai (2022-02-08 04:40:28)
> The pll clk type registration function does not stop or return errors
> if any clk failed to be registered, nor does it implement an error
> handling path. This may result in a partially working device if any
> step failed.
> 
> Make the register function return proper error codes, and bail out if
> errors occur. Proper cleanup, i.e. unregister any clks that were
> successfully registered, and unmap the I/O space, is done in the new
> error path.
