Subject: [PATCH v2 20/25] clk: sunxi-ng: a64: Use local parent references for CLK_FIXED_FACTOR

From: Chen-Yu Tsai <wens@csie.org>

With the new clk parenting code and CLK_FIXED_FACTOR_{HW,FW_NAME}
macros, we can reference parents locally via pointers to struct clk_hw
or DT clock-names.

Convert existing CLK_FIXED_FACTOR definitions to either the _HW or
_FW_NAME variant based on whether the parent clock is internal or
external to the CCU.
