rtc: do not use container_of macro as an argument for to_platform_device

Browse source 
The to_platform_device macro itself uses container_of macro.  Nested use
of container_of macro causes following sparse warnings:

rtc-ds1553.c:259:3: warning: symbol '__mptr' shadows an earlier one
rtc-ds1553.c:259:3: originally declared here
