i2c: Drop I2C_SLAVE_FROM_QDEV() macro

It is not being used in hot paths and is obsoleted by I2C_SLAVE()
QOM cast macro. Clean it up using a scripted conversion, so that it
doesn't get used in new code.

Some of its callers were combining it with FROM_I2C_SLAVE() macro, which
is equally obsolete but needs to be replaced in a type-specific way.
