MIPS: Loongson32: Remove reset.c
Commit 2a31bf20808a ("watchdog: loongson1_wdt: Implement restart handler")
implmented .restart ops, Then, _machine_restart is no longer needed.
The _machine_halt and pm_power_off are also unnecessary,
which contain no hardware operations.
Therefore, remove the entire reset.c and related header file.
Update the Makefile accordingly.
