MGS-6664-1 [#imx-2955] GPU AXI BUS error

Only 8MQ, 8MM, 8MN boards can't access 4G above memory and need to
set gcvPLATFORM_FLAG_LIMIT_4G_ADDRESS flagbits. Totalram_pages check doesn't
include kernel memory, reserved memory, causing this flagbits is not set and
AXI BUS error on customer's board. So we remove this redundant check.
