====================
net: phy: meson-gxl: clean-up and improvements

This patchset adds defines for the control registers and helpers to access
the banked registers. The goal being to make it easier to understand what
the driver actually does.
Then CONFIG_A6 settings is removed since this statement was without effect
Finally interrupt support is added, speeding things up a little

This series has been tested on the libretech-cc and khadas VIM

Changes since v2 [0]:
Drop LPA corruption fix which has been merged through net. Apart from this,
series remains the same.
