misc: issp: add issp driver support
Cypress in-system serial programming (ISSP) interface is used
to program Cypress micro controllers. This driver uses gpios
to simulate issp protocol.
Notes:
- Please make sure firmware is builtin before add device, because
the driver will hang on waiting for the firmware.
- If issp shares pins with other driver, please make sure the other
driver initialize after issp driver.
- It's better use firmware that disable version block read protect,
because the driver force firmware upgrade if the block's protected.
