The real time clocks ds1742 and ds1743 differs only in the size of the
nvram. This patch changes the existing ds1742 driver to support also
ds1743. The main change is that the nvram size is determined from the
resource attached to the device.
The patch have benefitted from suggestions from Atsushi Nemeto, who is the
author of the ds1742 driver.

Update RTC framework so that drivers can constify their method tables, moving
them from ".data" to ".rodata". Then update the drivers.
