spi: Get rid of flash_programmer_probe in spi_slave structure

flash_programmer_probe is a property of the spi flash driver and does
not belong in the spi_slave structure. Thus, make
spi_flash_programmer_probe a callback from the spi_flash_probe
function. Logic still remains the same as before (order matters):
1. Try spi_flash_programmer_probe without force option
2. Try generic flash probing
3. Try spi_flash_programmer_probe with force option

If none of the above steps work, fail probing. Flash controller is
expected to honor force option to decide whether to perform specialized
probing or to defer to generic probing.

BUG=None
BRANCH=None
TEST=Compiles successfully
