dt-bindings: i2c: renesas,rzv2m: Fix SoC specific string

The preferred form for Renesas' compatible strings is:
"<vendor>,<family>-<module>"

Somehow the compatible string for the r9a09g011 I2C IP was upstreamed
as renesas,i2c-r9a09g011 instead of renesas,r9a09g011-i2c, which
is really confusing, especially considering the generic fallback
is renesas,rzv2m-i2c.

The first user of renesas,i2c-r9a09g011 in the kernel is not yet in
a kernel release, it will be in v6.1, therefore it can still be
fixed in v6.1.
Even if we don't fix it before v6.2, I don't think there is any
harm in making such a change.

s/renesas,i2c-r9a09g011/renesas,r9a09g011-i2c/g for consistency.
