raiden_debug_spi: add param for a custom reset setup

GSC firmware asserts EC_RST_L before programming the AP with
raiden_debug:target=AP.Some Chromium devices don't power the AP flash
 when the EC is in reset. These boards can't flash the AP with the
current CCD behavior. This change adds a custom_rst raiden_debug param
to tell Cr50 not to assert EC_RST_L or touch any reset signals while
flashing the AP. Users will need to configure the reset signals before
running the flashrom command.


	flashrom -p raiden_debug:target=EC -r ec.bin

	flashrom -p raiden_debug:target=AP -r ap.bin

	flashrom -p raiden_debug:target=AP,custom_rst=true -r ap.bin

	flashrom -p raiden_debug:target=AP,custom_rst=inv -r ap.bin

	flashrom -p raiden_debug -r base.bin
