Subject: [PATCH 06/11] dt-bindings: thermal: k3-j72xx: conditionally require efuse reg range

Only some of TI's J721E SoCs will need a eFuse register range mapped to
determine if they're affected by TI's i2128 erratum. All other SoC will
not need this eFuse range to be mapped to function properly

Update the bindings for the k3_j72xx_bandgap thermal driver so other
devices will only need to define two register ranges
