[PATCH] openrisc: bump reserved size to 1M

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The macro used to be 256K back in 2011, and was bumped to 512K in 2014.
Now 11 years later, the image is about to grow beyond it.

As this limit seems to be arbitrary anyway, just double it again to 1M.

If a smaller size is indeed needed, it should be enforced over
BAREBOX_MAX_IMAGE_SIZE instead. For QEMU and testing in CI, 1M is fine
though and we need not bother with keeping generic_defconfig small.
