The Ameba RTC driver converts time_t to second/minute/hour/day/month/year in rtc_write and back to time_t in rtc_read. Replace this with an implementation which uses time_t directly.
The use of mktime was causing a fault when called in interrupt handler because on GCC it lock the mutex protecting the environment, To overcome this issue, this patch add dedicated routine to convert a time_t into a tm and vice versa. In the process mktime has been optimized and is now an order of magnitude faster than the routines present in the C library.

@mazimkhan Can you help to restart uvisor for this patch (or might listen to my command few minutes later?) |
This field is necessary, it is used by several vendor RTC: Atmel, ST, NUVOTON, NXP.
This field is needed by the LPC43XX targets.

Remove usage of mktime and localtime from RTC drivers. This PR was taken from #4479 and expanded to cover all the targets since they have the same issue as ST devices. @pan- feel free to modify this as necessary.
