arm: socfpga: gen5: fix ERR_PTR_OFFSET
The default implementation of ERR_PTR/PTR_ERR maps errno values at the
and of the address range (e.g. -EINVAL/-22 gets 0xFFFFFFEA).
For socfpga gen5 SPL, this doesn't really work, as the heap is nearly
at the end of the 32 bit address range.
This patch adjusts the ERR_PTR_OFFSET to map errno values into the range
of the Boot ROM, which should not be used for valid pointers.
