When subsampling is enabled as a viewfinder mode, and the sensor is switched back
and forth between full resolution and subsampling, it is recommended that
line_length_pck be kept constant between the two modes. This allows the same integra-
tion times to be used in each mode.
When subsampling is enabled, it may be necessary to adjust the x_addr_end and
y_addr_end settings. The values for these registers are required to correspond with rows/
columns that form part of the subsampling sequence. The adjustment should be made
in accordance with the following rule:
remainder = (addr_end - addr_start + 1) AND 0x0002;
if (remainder == 0) addr_end = addr_end - 2;
