Subject: [PATCH 1/2] arm64: dts: exynos: drop unsupported I2C properties in Espresso

The Samsung HSI2C (High Speed I2C) bindings do not allow
samsung,i2c-sda-delay (present in older S3C24xx I2C bindings):

  exynos7-espresso.dtb: i2c@...60000: Unevaluated properties are not allowed ('samsung,i2c-sda-delay', 'samsung,i2c-max-bus-freq' were unexpected)
