[PATCH 1/2] sandbox: Fix DT compiler address warnings in sandbox DTs

[Marek Vasut]

Trivially fix the following warnings in sandbox DTs, which show up with
DTC 1.7.2. Fill in the missing address and adjust emulated I2C address
to fit the 7bit address limit:

"
arch/sandbox/dts/sandbox.dtsi:138.30-140.5: Warning (i2c_bus_reg): /i2c@0/sandbox_pmic: I2C bus unit address format error, expected "40"
arch/sandbox/dts/sandbox.dtsi:146.18-161.5: Warning (i2c_bus_reg): /i2c@0/emul: I2C bus unit address format error, expected "ff"
arch/sandbox/dts/sandbox.dtsi:148.4-17: Warning (i2c_bus_reg): /i2c@0/emul:reg: I2C address must be less than 7-bits, got "0xff". Set I2C_TEN_BIT_ADDRESS for 10 bit addresses or fix the property
"

"
arch/sandbox/dts/.test.dtb.pre.tmp:912.18-926.5: Warning (i2c_bus_reg): /i2c@0/emul: I2C bus unit address format error, expected "ff"
arch/sandbox/dts/.test.dtb.pre.tmp:913.4-17: Warning (i2c_bus_reg): /i2c@0/emul:reg: I2C address must be less than 7-bits, got "0xff". Set I2C_TEN_BIT_ADDRESS for 10 bit addresses or fix the property
arch/sandbox/dts/.test.dtb.pre.tmp:928.30-931.5: Warning (i2c_bus_reg): /i2c@0/sandbox_pmic: I2C bus unit address format error, expected "40"
"

Fix up pmic test to match.

[PATCH 2/2] sandbox: Fix DT compiler pin warnings in sandbox DTs

[Marek Vasut]

Trivially fix the following warnings in sandbox DTs, which show up with
DTC 1.7.2. Assign pin groups less confusing node names with pins- prefix
to avoid confusing DT compiler into thinking the node is really a bus node:
