of: reserved_mem: Allow reserved_mem framework detect "cma=" kernel param
[ Upstream commit 0fd17e5983337231dc655e9ca0095d2ca3f47405 ]
When initializing the default cma region, the "cma=" kernel parameter
takes priority over a DT defined linux,cma-default region. Hence, give
the reserved_mem framework the ability to detect this so that the DT
defined cma region can skip initialization accordingly.
