pinctrl: sunxi: a523-r: add a733-r compatible string

The secondary Allwinner A733 pincontroller ("-r") is interestingly not
using the same new MMIO frame layout as the main controller, but is in
fact very similar to the A523-r one: it has two banks, with 14 and 6 pins
each. From the driver's perspective, this is all we care about, so we can
re-use the a523-r pinctrl driver for the a733-r, too.

The individual pinmux settings are different, so we must not use the
a523-r compatible string as a fallback, but we can surely let the same
driver care for both the a523-r and a733-r IP, as the pinmux values will
be provided by the DT.

Add the a733-r compatible string to the match list, without further
distinguishing between the two. Should differences be discovered later,
we can easily split this up then.
