usb: typec: fsa4480: Relax CHIP_ID check
Some FSA4480-compatible chips like the OCP96011 used on Fairphone 5
return 0x00 from the CHIP_ID register. Handle that gracefully and only
fail probe when the I2C read has failed.
With this the dev_dbg will print 0 but otherwise continue working.
[ 0.251581] fsa4480 1-0042: Found FSA4480 v0.0 (Vendor ID = 0)
