i2c-i801: Clear only status bits in HST_STS Writing back the whole status register could clear unwanted bits. In particular, it could clear the "INUSE_STS" bit, which is a 'hardware semaphore', that might be useful to use some day. To prepare for this, let's ban writing back the whole status to register HST_STS, of which this is the only instance.
