Alexandru Gagniuc b5669ba579 drivers/pc80/mc146818rtc: Reduce superfluous preprocessor use
cmos_init() had layers of preprocessor directives, which resulted in
a complete mess. Refactor it to make use of the IS_ENABLED() macro.
This improves readability significantly.

One of the changes is to remove in inline stub declaration of
(get|set)_option. Although that provided the ability for the compiler
to optimize out code when USE_OPTION_TABLE is not selected, there is
no evidence that such savings are measureable.
