Two bugs have sneaked in the H616 pinctrl data:
- PH9 uses the mux value of 0x3 twice (one should be 0x5 instead)
- PH8 and PH9 use the "i2s3" function name twice in each pin
For the double pin name we use the same trick we pulled for i2s0: append
the pin function to the group name to designate the special function.
Fixes: 25adc29407fb ("pinctrl: sunxi: Add support for the Allwinner H616 pin controller")

Signed-off-by: Andre Przywara <andre.przywara@arm.com>Reviewed-by: Samuel Holland <samuel@sholland.org> Verified against the manual, which ironically also has the function numbers wrong: it lists two function 4's (and no function 5) for each pin in port H.
