[PATCH v4 0/4] spi: spi-mtk-nor: Add mt8192 support.

[Ikjoon Jang <ikjn@xxxxxxxxxxxx>]

This patchset adds 36bit dma address and power management
supports for mt8192-nor. Additionally, use dma_alloc_coherent()
instead of kmalloc() for internal bounce buffer for platforms
of only supporting 32bit addresses.

Changes in v4:
- Drop two patches from a list which already addressed by
  an another series and not directly related with mt8192 support
- Fix 0-day ci 'shift-count-overflow' warning
- Fix missing 'high_dma' initialization for 36bit address

Changes in v3:
- Fix a bugfix of v2 in checking spi memory operation.
- split read_dma function into two (normal/bounce)
- Support 7bytes generic spi xfer

Changes in v2:
- Add power management support
- Fix bugs in checking spi memory operation.
- use dma_alloc_coherent for allocating bounce buffer
- code cleanups
