Although this is just "moving code", we need this priv to do some
modification for mt798x_phy_hw_led_blink_set() so that we can move it
to mtk-phy-lib properly.
I was trying to split this patch into two but I'm afraid that will make
this patchset more complex. Is it okay that I add more explanation in
commit message? like:
This patch creates mtk-phy-lib.c & mtk-phy.h and integrates mtk-ge-
soc.c's LED helper functions so that we can use those helper functions
in other MTK's ethernet phy driver.
We need private data passed to
- mtk_phy_hw_led_on_set()
- mtk_phy_hw_led_blink_set()
- mtk_phy_led_hw_ctrl_get()
- mtk_phy_led_hw_ctrl_set()
to make sure these helper functions can be used in both mtk-ge-soc.c &
mtk-ge.c.
