An array of maximum supported image sizes in pixels, for details refer to
Table 2-1 in the S5PV210 SoC User Manual. The meaning of each cell is as
follows:
0 - scaler input horizontal size

A bitmask specifying whether this IP has the input and the output
rotator. Bits 4 and 0 correspond to input and output rotator
respectively. If a rotator is present its corresponding bit should be
set.
