Ming Wang 20f0f55e6d rtc: loongson: clear TOY_MATCH0_REG in loongson_rtc_isr() 
[ Upstream commit 09471d8f5b390883eaf21b917c4bf3ced1b8a1df ]

The TOY_MATCH0_REG should be cleared to 0 in the RTC interrupt handler,
otherwise the interrupt cannot be cleared, which will cause the
loongson_rtc_isr() to be triggered multiple times.

The previous code cleared TOY_MATCH0_REG in the loongson_rtc_handler(),
which is an ACPI interrupt. This did not prevent loongson_rtc_isr()
from being triggered multiple times.

This commit moves the clearing of TOY_MATCH0_REG to the
loongson_rtc_isr() to ensure that the interrupt is properly cleared.
