arm64: zynqmp: Do not duplicate flash partition label property

[ Upstream commit 167721a5909f867f8c18c8e78ea58e705ad9bbd4 ]

In kernel 5.4, support has been added for reading MTD devices via the nvmem
API.
For this the mtd devices are registered as read-only NVMEM providers under
sysfs with the same name as the flash partition label property.

So if flash partition label property of multiple flash devices are
identical then the second mtd device fails to get registered as a NVMEM
provider.

This patch fixes the issue by having different label property for different
flashes.
