6ddab92faa rtc: sunxi: constify the data_year_param structure
The data_year_param struct is never modified, so lets constify it.
This permit to remove cast since of_device_id is const also.

f8947feb2c rtc: sunxi: fix signedness issues
The variable year must be set as unsigned since it is used with
sunxi_rtc_data_year{.min|.max} and as parameter of is_leap_year() which
wait for unsigned int.
Only tm_year is not unsigned, but it is long.
This patch fix also the format of printing of min/max. (must use %u since
they are unsigned)

The parameter to of sunxi_rtc_setaie() must be set to uint since callers
give always uint data.

9033fd8ba7 rtc: sunxi: Replace deprecated rtc_tm_to_time()
sunxi_rtc_setalarm() uses deprecated rtc_tm_to_time(),
which will overflow in year 2106 on 32-bit machines.

This patch solves this by:
- Replacing rtc_tm_to_time() with rtc_tm_sub()

Also remove the unnecessary initial zeroing of some
local variables in sunxi_rtc_setalarm().

A platform_driver does not need to set an owner, it will be populated by the
driver core.

f49bd06e1d rtc: sunxi: change compatibles
The Allwinner A10 compatibles were following a slightly different
compatible patterns than the rest of the SoCs for historical reasons.
Change the compatibles to match the other pattern in the RTC driver for
consistency.
