[PATCH v2 2/5] ASoC: rockchip: spdif: Reorder clock enable sequence

[phucduc.bui at gmail.com]

From: bui duc phuc <phucduc.bui at gmail.com>

Enable the 'hclk' bus clock before the 'mclk' controller clock during
runtime resume.
The bus clock provides the register access interface, so enable it before
the controller clock. This also makes the resume sequence the reverse of
the suspend sequence, which keeps the clock ordering consistent.

NOTE: This patch is compile-tested only. Please help test if you have 
    the relevant Rockchip hardware.
Changes in v2:
  - Clarify in the commit message that the resume sequence becomes the
    reverse of the suspend sequence.
