ARM: dts: bcm283x: Drop unnecessary properties from dpi node

Since commit 09453600 ("dt-bindings: display: Convert
VC4 bindings to schemas") it has been defined that the properties
'#address-cells' and '#size-cells' are not necessary for the dpi
node. This results in a warning during dtbs_check:

  dpi@7e208000: '#address-cells', '#size-cells' do not match any
  of the regexes: 'pinctrl-[0-9]+'

Since we don't need a reg property to differentiate between
multiple ports, drop them from the dtsi file.
