Subject: [PATCH 0/5] i2c: RTL9300 support

This builds on top of my in-flight series that adds the syscon node for the
switch block[1]. The I2C controllers are part of that block of registers. The
controller driver is adapted from openwrt, the multiplexing support is added by
me and differs from the openwrt implementation.
