89ba361fcc The year is stored in a single byte in sram, in binary format, as a count 
of years since the century, so strip the century out when converting to or
from bcd_clocktime format (the conversion routines will infer century by
pivoting on 70).

5deff57b6f Convert to the new(ish) bcd_clocktime conversion functions, add calls to 
the new debug output functions, and when setting the clock, propagate the
timespec nsecs to the 1/100ths register.

be04c94e1e [i2c/clock] add support for EPSON RTC-8583 
RTC-8583 is time-of-day clock used in some SOHO routers. This clock has
only 2 bits for year values, but thanks to user SRAM it's possible to save
year value and keep it up to date via driver code.

Tested on Planex_MZK-W300NAG (SoC is RT2880)
