[PATCH v2 00/11] enable VTM node for all TI's K3 SoCs

Hello again everyone!

This series enabled the VTM nodes for all of Texas Instruments K3 SoCs

Most of this series updates the k3_j72xx_bandgap driver to conditionally
map an eFuse region used by the j721e to work around an issue in its VTM
implementation and allows us to save the SPARE_FUSE region on other SoCs

We can then update the device tree bindings for the driver and finally
define the VTM nodes for each device

Thanks for reviewing!

****

v1 -> v2 changes[0]:

- when removing 'fuse_base' from the 'k3_j72xx_bandgap' structure, I
forgot to pass 'fuse_base' to get_efuse_values()

- removed the descriptions to the generic 'power-domains' property

- incorporated Krzysztof's suggestions to the binding description

- refactored binding to use allOf: if: {min,max}Items over what I was
doing :) Thanks Krzysztof
