Subject: [18/70] ARM: pxa168: correct nand pmu setting

2.6.39-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Lei Wen <leiwen@...vell.com>

commit 6662498e132dfa758925a160fd5ef80a083651c3 upstream.

The original pair of <0x01db, 208000000> is invalid. Correct it to
the valid value.

The 6th bit of the NFC APMU register indicates NFC works whether
at 156Mhz or 78Mhz. So 0x19b indicates NFC works at 156Mhz, and
0x1db indicates it works at 78Mhz.
