[PATCH] nvmem: core: fix nvmem_layout_get_match_data()

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This function was trying to match wrong OF node (parent device's)
against an of_match_table. It was always returning NULL.

Make it match layout's OF node against layout's of_match_table.

Fixes: f5709a684a0a ("nvmem: core: introduce NVMEM layouts")
