[v3,0/3] Add initialization of clock for StarFive JH7110 SoC

Hi,

This patchset adds initial rudimentary support for the StarFive
Quad SPI controller driver. And this driver will be used in
StarFive's VisionFive 2 board. In 6.4, the QSPI_AHB and QSPI_APB
clocks changed from the default ON state to the default OFF state,
so these clocks need to be enabled in the driver.At the same time,
dts patch is added to this series.

Changes v1->v2:
- Rebaed to v6.4rc6.
- Renamed the clock names.
- Changed the variable definition type.

Changes v1->v2:
- Renamed the clock names.
- Specified a different array of clocks.
- Used clk_bulk_ APIs.

The patch series is based on v6.4rc6.
