PCI: rockchip: Simplify clock handling by using clk_bulk*() functions

Browse source

Currently, the driver acquires clocks and prepare/enable/disable/unprepare
the clocks individually thereby making the driver complex to read.

The driver can be simplified by using the clk_bulk*() APIs.

Use:

  - devm_clk_bulk_get_all() API to acquire all the clocks
  - clk_bulk_prepare_enable() to prepare/enable clocks
  - clk_bulk_disable_unprepare() APIs to disable/unprepare them in bulk
