Some IPs have their accessible address space restricted by the
interconnect. Let's make sure U-Boot only ever uses the space below
the 4G address boundary (which is 3GiB big), even when the effective
available memory is bigger.
We implement board_get_usable_ram_top() for all i.MX8M SoCs, as the
whole family is affected by this.
Shouldn't only those specific IP drivers handle buffers in the 64bit
space somehow ? E.g. using a bounce buffer ?
