Subject: [PATCH 4.9 173/175] clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9

From: Terry Zhou <bjzhou@...vell.com>

commit 6f37689cf6b38fff96de52e7f0d3e78f22803ba0 upstream.

There is an error in the current code that the XTAL MODE
pin was set to NB MPP1_31 which should be NB MPP1_9.
The latch register of NB MPP1_9 has different offset of 0x8.
