thermal: imx_tmu: extend with QorIQ/Layerscape TMU
Add support for the on-die Thermal Monitoring Unit (TMU) of the
new QorIQ/Layerscape SoCs (LX2160A, LS1028A, LS1088A, ...):
examples on a lx2160:
=> temperature list
| Device | Driver | Parent
| tmu@1f80000 | imx_tmu | root_driver
| cluster67-thermal | imx_tmu | tmu@1f80000
| ddr1-cluster5-thermal | imx_tmu | tmu@1f80000
| wriop-thermal | imx_tmu | tmu@1f80000
| dce-qbman-hsio2-thermal | imx_tmu | tmu@1f80000
| ccn-dpaa-tbu-thermal | imx_tmu | tmu@1f80000
| cluster4-hsio3-thermal | imx_tmu | tmu@1f80000
| cluster23-thermal | imx_tmu | tmu@1f80000
=> temperature get tmu@1f80000
tmu@1f80000: 82000 mC
=> temperature get wriop-thermal
wriop-thermal: 81000 mC
The parent tmu@... node owns the MMIO and calibration; one
UCLASS_THERMAL device is bound per/thermal-zones site so each shows
up by its zone name:
=> dm tree
...
thermal 2 [ + ] imx_tmu |-- tmu@1f80000
thermal 3 [ + ] imx_tmu | |-- cluster67-thermal

The dtsi additions mirror the existing fsl-ls1028a.dtsi: the LX2160A
SoC dtsi gains the tmu@1f80000 node plus a thermal-zones hierarchy
with 7 sites:
cluster67-thermal site 0 A72 clusters 6 + 7
ddr1-cluster5-thermal site 1 DDR1 + A72 cluster 5
wriop-thermal site 2 WRIOP
dce-qbman-hsio2-thermal site 3 DCE + QBMAN + HSIO2
ccn-dpaa-tbu-thermal site 4 CCN508 + DPAA + TBU
cluster4-hsio3-thermal site 5 A72 cluster 4 + HSIO3
cluster23-thermal site 6 A72 clusters 2 + 3
