spi: intel: 64k erase is supported from Canon Lake and beyond
The hardware sequencer in Intel Canon Lake and beyond supports also 64k
erase command. The SPI-NOR core uses SFDP (Serial Flash Discovery
Parameter) to figure out what the chip actually supports and only issues
64k erase if it is supported.
