ARM: SoC fixes

Browse Source 
A few smaller fixes for v5.7-rc3: The majority are fixes for bugs I found
 after restarting my randconfig build testing that had been dormant for
 a while.
 
 On the Nokia N950/N9 phone, a DT fix is required to address a boot
 regression.
 
 For the bcm283x (Raspberry Pi), two DT fixes address minor issues.

If you say yes here you get support for the NXP i.MX8M family
support, it will provide the SoC info like SoC family,
