dts-bindings: pinctrl: renesas_ra: enabled config of i/o ports 4-7

Browse source 
The RA_PINCFG macro is used to generate a value that can be written
directly to the pin function select register. In addition to the pin
function this value also contains port and pin number information,
located in bit fields that are unused by the register. The bit field
used to store the port information consists of 3-bits. However, a typo in
the mask definition limited the field to two bits meaning only ports 0-3
could be configured. This patch resolves the issue, allowing ports 0-7 to
be configured. If the port is greater than 7 another field (port4) is used
to store an additional bit (allowing an additional 8 ports to be
supported). However, use of this field has not yet been implemented.
