Subject: [PATCH v2 0/3] riscv: rtc: sophgo: add rtc support for CV1800

This series adds rtc support for Sophgo CV1800.

Changes since v1
- fix duplicate names in subject
- using RTC replace RTC controller
- improve the properties of dt-bindings
- using `unevaluatedProperties` replace `additionalProperties`
- dt-bindings passed the test
- using `devm_platform_ioremap_resource()` replace
  `platform_get_resource()` and `devm_ioremap_resource()`
- fix random order of the code
- fix wrong wrapping of the `devm_request_irq()` and map the flag with dts
- using devm_clk_get_enabled replace `devm_clk_get()` and
  `clk_prepare_enable()`
- fix return style
- add rtc clock calibration function
- use spinlock when write register on read/set time
