Subject: [PATCH v2 5/5] clk: Ingenic: Clean up and reformat the code.

1.When the clock does not have "CGU_CLK_MUX", the 2/3/4 bits in
  parents do not need to be filled with -1. When the clock have
  a "CGU_CLK_MUX" has only one bit, the 3/4 bits of parents do
  not need to be filled with -1. Clean up these unnecessary -1
  from all the xxxx-cgu.c files.
2.Reformat code, add missing blank lines, remove unnecessary
  commas and tabs, and align code.

Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@...yeetech.com>
---

Notes:
    v1->v2:
    Remove unnecessary -1 and commas.
