ARM: dts: Fix dcan driver probe failed on am437x platform
Got following d_can probe errors with kernel 5.8-rc1 on am437x
[ 10.730822] CAN device driver interface
Starting Wait for Network to be Configured...
[ OK ] Reached target Network.
[ 10.787363] c_can_platform 481cc000.can: probe failed
[ 10.792484] c_can_platform: probe of 481cc000.can failed with error -2
[ 10.799457] c_can_platform 481d0000.can: probe failed
[ 10.804617] c_can_platform: probe of 481d0000.can failed with error -2
actually, Tony has fixed this issue on am335x with the patch [3]
Since am437x has the same clock structure with am335x
[1][2], so reuse the code from Tony Lindgren's patch [3] to fix it.
