Add the necessary clocks for i2c0 to i2c3 into the mstp3 clock node. This
is a pre-cursor to adding the i2c devices themslves.

According to the R8A7790 datasheet the I2C MSTP clocks are handled by MSTP9,
not MSTP3, and they're already declared in the MSTP9 DT node.

Ah, the i2cX nodes themselves are wrong.
i2c1: i2c@e6518000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "renesas,i2c-r8a7790";
reg = <0 0xe6518000 0 0x40>;
interrupt-parent = <&gic>;
interrupts = <0 288 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp3_clks R8A7790_CLK_I2C1>;
status = "disabled";
};

Indeed, my bad. Would you like to submit a patch to fix this, or should I do
it ?
