drm/sun4i: hdmi: create a regmap for later use
The HDMI driver is written with readl/writel I/O to the registers.
However, to support the A31 variant, which has a different layout
for the DDC registers, it was recommended to use regfields to have
a cleaner implementation. To use regfields, we need to create an
underlying regmap.
This patch only adds the regmap. It does not convert the existing
driver accesses to use regmap.
