With the exception of i2c10 and i2c11 which conflict with the pins
for the third and forth MDIO controllers.

i2c0 has an ADT7490 fan controller/thermal monitor device connected. The
devicetree describes an adt74490 on i2c0, however bus that it appears on
depends on jumper settings, so it may not be present on all EVBs. It is
included to assist testing of I2C.

Requesting pinmux configuration is done at driver probe time. The LPC IP
is composed of many sub-devices, each with their own driver, and no
driver exists for the entire IP block. Avoid having each sub-device
request the LPC pinmux by just hogging it in the pinctrl node.
