thermal/drivers/k3_j72xx_bandgap: Remove fuse_base from structure 



'fuse_base' is only needed during the initial probe function to provide
data for a software trimming method for some of TI's devices affected by
the i2128 erratum. The devices not affected will not use this region

Remove fuse_base from the main k3_j72xx_bandgap structure
