ARM: dts: ls1021a: fix QuadSPI-memory reg range
[ Upstream commit 81dbbb417da4d1ac407dca5b434d39d5b6b91ef3 ]
According to the Reference Manual, the correct size is 512 MiB.
Without this fix, probing the QSPI fails:
fsl-quadspi 1550000.spi: ioremap failed for resource
[mem 0x40000000-0x7fffffff]
fsl-quadspi 1550000.spi: Freescale QuadSPI probe failed
fsl-quadspi: probe of 1550000.spi failed with error -12
