checks: Update #{size,address}-cells check for 'dma-ranges'
The "dma-ranges" property value is a sequence of
child-address parent-address child-size
The size of each field is determined by taking the child's
"#address-cells" value, the parent's "#address-cells" value,
and the child's "#size-cells" value.
However, in the following example, it gives a false alarm:
+-----------------------------------+---------------------------------------+
| ranges.dts | dma-ranges.dts |
+-----------------------------------+---------------------------------------+
| /dts-v1/; | /dts-v1/; |
| | |
| /{ | /{ |
| #address-cells = <1>; | #address-cells = <1>; |
| | |
| parent { | parent { |
| #address-cells = <1>; | #address-cells = <1>; |
| #size-cells = <1>; | #size-cells = <1>; |
| ranges = <0x0 0xe000 0x1000>; | dma-ranges = <0x0 0xe000 0x1000>; |
| child { | child { |
| ... | ... |
| }; | }; |
| }; | }; |
| }; | }; |
+-----------------------------------+---------------------------------------+
| no warning | Warning (avoid_unnecessary_addr_size) |
+-----------------------------------+---------------------------------------+
Same as "ranges", it should not be reported in this check.
