Subject: mtd: pxa3xx_nand: add a default chunk size

From: =?UTF-8?q?Antoine=20T=C3=A9nart?= <antoine.tenart@free-electrons.com>

commit bc3e00f04cc1fe033a289c2fc2e5c73c0168d360 upstream.

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.

support")
