Subject: [PATCH] mtd: pxa3xx_nand: add a default chunk size

When keeping the configuration set by the bootloader (by using
the marvell,nand-keep-config property), the pxa3xx_nand_detect_config()
function is called and set the chunk size to 512 as a default value if
NDCR_PAGE_SZ is not set.

In the other case, when not keeping the bootloader configuration, no
chunk size is set. Fix this by adding a default chunk size of 512.

Fixes: 70ed85232a93 ("mtd: nand: pxa3xx: Introduce multiple page I/O
support")
