lspcon_i2c_spi.c: Add SPI-master support for PS17{5,6}
This adds support for the Parade lspcon usb-c to HDMI protocol translater part that is i2c-controlled. The support allows the host to reach the SPI ROM that hangs off the part where it stores its firmware. Usage is as follows: flashrom -p lspcon_i2c_spi:bus=X where X is the bus number. BUG=b:148746232 BRANCH=none TEST=tested with following commands, read/write/erase works good. flashrom -p lspcon_i2c_spi:bus=7 -r /tmp/foo; flashrom -p lspcon_i2c_spi:bus=7 -E; flashrom -p lspcon_i2c_spi:bus=7 -w /tmp/foo; Change-Id: I039e683252cfaf1ffef8694a3e8081b1b6b944f7 Signed-off-by: Shiyu Sun <sshiyu@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/39687 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org>
