Subject: [PATCH v2] ARM: dts: at91: sama5d2: Fix PMERRLOC resource size

PMERRLOC resource size was set to 0x100, which resulted in HSMC_ERRLOCx
register being truncated to offset x = 21, causing error correction to
fail if more than 22 bit errors and if 24 or 32 bit error correction
was supported.

Fixes: d9c41bf30cf8 ("ARM: dts: at91: Declare EBI/NAND controllers")
