Using uint16_t instead of uint32_t reduces code size
and probably is quicker to execute
OCR4C register is 2 bytes on ATmega2560
It's 1 byte on ATmega32u4 and ATmega16u4
Change in memory:
Flash: -80 bytes
SRAM: 0 bytes
Instead of including Configuration_prusa.h directly, include
Configuration_var which then includes the proper variant file though a
preprocessor macro.
This allows to keep the existing build system intact, but also redefine
at compile time the final header without having to make copies on the
file system.
