pinctrl: sh-pfc: r8a7795: remove duplicate of CLKOUT pin in pinmux_pins[]

When adding GP-1-28 port pin support it was forgotten to remove the
CLKOUT pin from the list of pins that are not associated with a GPIO
port in pinmux_pins[]. This results in a warning when reading the
pinctrl files in sysfs as the CLKOUT pin is still added as a none GPIO
pin. Fix this by removing the duplicated entry which is no longer
needed.
