[PULL 20/49] hw/display/omap_lcdc: Expand out macros in template header

[Peter Maydell <peter.maydell@linaro.org>]

The omap_lcdc template header is already only included once, for
DEPTH==32, but it still has all the macro-driven parameterization
for other depths. Expand out all the macros in the header.
