calibrate: Rework delay timer calibration
The header define in asm/timex,h and the naming of the function to read the
delay timer are confusing at best.
Convert it to a config switch selected by the archictures which provide the
functionality and rename the function to delay_read_timer(), which makes
the purpose clear. Move the declaration to linux/delay.h where it belongs.
Remove the resulting empty asm/timex.h files as well.
No functional change.
