Changes in v4:
  - Reword 'legacy' to 'default'
  - Rename spi_nor_read() to spi_nor_default_ready()
  - Fix dummy cycle calculation in spansion_read_any_reg()
  - Modify comment for spansion_write_any_reg()
  - Merge block comments about SMPT in s25hx_t_post_sfdp_fixups()
  - Remove USE_CLSR flags from S25HL02GT and S25HS02GT

Changes in v3:
