rtc: BCD codeshrink
This updates <linux/bcd.h> to define the key routines as constant
functions, which the macros will then call. Newer code can now call
bcd2bin() instead of SCREAMING BCD2BIN() TO THE FOUR WINDS.
This lets each driver shrink their codespace by using N function calls to
a single (global) copy of those routines, instead of N inlined copies of
these functions per driver.
These routines aren't used in speed-critical code. Almost all callers are
in the RTC framework. Typical per-driver savings is near 300 bytes.
