ARM: bcm2835: fix I2C module clock rate
BCM2835-ARM-Peripherals.pdf states that the I2C module's input clock is
nominally 150MHz, and that value is currently reflected in bcm2835.dtsi.
However, practical measurements show that the rate is actually 250MHz,
and this agrees with various downstream kernels.
Switch the I2C clock's frequency to 250MHz so that the generated bus
clock rate is accurate.
