Eugen Hristev 66d9f5214c clk: at91: sam9x60: fix programmable clock prescaler 
The prescaler works as parent rate divided by (PRES + 1) (is_pres_direct == 1)
It does not work in the way of parent rate shifted to the right by (PRES + 1),
which means division by 2^(PRES + 1) (is_pres_direct == 0)
Thus is_pres_direct must be enabled for this SoC, to make the right computation.
This field was added in
commit 45b0668211 ("clk: at91: fix programmable clock for sama5d2")
SAM9X60 has the same field as SAMA5D2 in the PCK
