[PATCH 1/3] dt-bindings: mfd: st,stmpe: add deprecated properties

[Frank.Li@oss.nxp.com]

From: Frank Li <Frank.Li@nxp.com>

Add deprecated properties st,sample-time, st,sample-time, st,mod-12b and
st,ref-sel. The both driver drivers/mfd/stmpe.c and
drivers/input/touchscreen/stmpe-ts.c parse these information. Some dts
put these properties under mfd, but some put these under child node
sample_ts.

Allow these properties put under sample_ts and mark as deprecated to fix
below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/imx/imx6q-novena.dtb: stmpe811@44 (st,stmpe811): touchscreen: Unevaluated properties are not allowed ('st,adc-freq', 'st,mod-12b', 'st,ref-sel', 'st,sample-time' were unexpected)
        from schema $id: http://devicetree.org/schemas/mfd/st,stmpe.yaml
