thermal: imx_tmu: Always set thermal trips from fuses

NXP i.MX SoCs are available in different temperature grades. By default,
device-tree contains only thermal trips for consumer grade parts. On the
other hand, part temp grade fuse can be used to determine thermal trip
points. We already do this in imx_tmu_bind() function. Now, factor out
this functionality to a standalone function imx_tmu_set_trips() and use
it for both cases. This fixes an issue where 'cpu-thermal' child device
would set different thermal trips than the parent 'tmu@44482000' sensor,
depending on which gets used.
