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;
