Why is this exclusive to AM62a? We could have this fixup work K3 wide with the
values defaulting to the correct one depending on the SOC similar to how we
handle the different load addresses for TFA with CONFIG_K3_ATF_LOAD_ADDR.
This would avoid the need for #ifdef in the next patch too.

   config K3_DM_FW_RESERVED_ADDR
     hex "Start address of DM firmware reserved memory region"
     default 0x9db00000 if SOC_K3_AM625
     default 0x9c900000 if SOC_K3_AM62A7
     ...

and same for the size.
