KASan: fix handling of devices with MMIO above SDRAM memory region

check_memory_region_inline will discard KASan reports before start of
RAM as false positives. This is sufficient for i.MX SoCs where the RAM
starts after all device MMIO regions. On the AT91, the EBI memory
controller's memory region follows the SDRAM memory region. This
results in a KASan warning the first time NAND is accessed.

Record the end of the shadowed SDRAM area to fix this.
