No one is using regs-clk.h and regs-rtc.h.
Therefore, remove these obsolete header files.

2.39.2
Since commit 35508d242409 ("MIPS: loongson32: ls1c: Fix hang
during startup"), no one is calling ls1x_rtc_set_extclk().
Therefore, remove this obsolete function.
Since commit 9fb23090658a ("rtc: Remove the Loongson-1
RTC driver"), no one is using regs-rtc.h.
Therefore, remove this obsolete header file.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
