On the Allwinner R40, the "GMAC clock" register is located in the CCU
block, at a different register address than the other SoCs that have
it in the "system control" block.
This patch converts the use of regmap to regmap_field for mapping and
accessing the syscon register, so we can have the register address in
the variants data, and not in the actual register manipulation code.
This patch only converts regmap_read() and regmap_write() calls to
regmap_field_read() and regmap_field_write() calls. There are some
places where it might make sense to switch to regmap_field_update_bits(),
but this is not done here to keep the patch simple.
