MIPS: loongson32: Remove regs-rtc.h

Browse Source 
Since commit 35508d2424 ("MIPS: loongson32: ls1c: Fix hang
during startup"), no one is calling ls1x_rtc_set_extclk().
Therefore, remove this obsolete function.

Since commit 9fb2309065 ("rtc: Remove the Loongson-1
RTC driver"), no one is using regs-rtc.h.
Therefore, remove this obsolete header file.
