[PATCH v3 2/2] ARM: dts: st: spear: remove undocumented thermal_flags property

[Gopi Krishna Menon <krishnagopi487@gmail.com>]

spear13xx.dtsi defines a thermal_flags property in spear thermal sensor
node which is both unused in kernel and undocumented in spear thermal
sensor's binding.

There were no dtbs_check warnings associated with this property as the
underlying spear thermal binding was not converted to DTSchema.

Most likely st,thermal-flags is a misspelling of thermal_flags in
spear13xx.dtsi. Since both st/spear1310.dtsi and st/spear1340.dtsi
define st,thermal-flags property in spear thermal sensor node, we can
safely remove this property from spear13xx.dtsi.
