09471d8f5b rtc: loongson: clear TOY_MATCH0_REG in loongson_rtc_isr()
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.

8c28c4993f rtc: use boolean values with device_init_wakeup()
device_init_wakeup() second argument is a bool type. Use proper boolean
values when calling it to match the type and to produce unambiguous code
which is easier to understand.

e5eab1aeae rtc: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/rtc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

1b733a9ebc rtc: Add rtc driver for the Loongson family chips
The Loongson family chips use an on-chip counter 0 (Time Of Year
counter) as the RTC. We will refer to them as rtc-loongson.
