Nicolas Ferre a80980225a clk: at91: clk-sam9x60-pll: force write to PLL_UPDT register 
[ Upstream commit af98caeaa7 ]

This register is important for sequencing the commands to PLLs, so
actually write the update bits with regmap_write_bits() instead of
relying on a read/modify/write regmap command that could skip the actual
hardware write if the value is identical to the one read.

It's changed when modification is needed to the PLL, when
read-only operation is done, we could keep the call to
regmap_update_bits().

Add a comment to the sam9x60_div_pll_set_div() function that uses this
PLL_UPDT register so that it's used consistently, according to the
product's datasheet.
