Subject: [PATCH 3.13 044/105] ARM: at91/PMC: don't forget to write PMC_PCDR register to disable clocks

3.13.11.10 -stable review patch.  If anyone has any objections, please let me know.

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

From: Ludovic Desroches <ludovic.desroches@...el.com>

commit cfa1950e6c6b72251e80adc736af3c3d2907ab0e upstream.

When introducing support for sama5d3, the write to PMC_PCDR register has
been accidentally removed.
