mx25: fix clock's calculation
* get_rate_arm : when 400MHz clock is selected (cctl & 1<<14),
ARM clock is 400MHz (MPLL * 3 / 4) and not 800MHz
* get_rate_per : peripherals's clock is derived from AHB and not
from IPG (ref manual : figure 5-1)
* can2_clk : use the correct ID
* without this patch, peripherals getting their clock from PER
clocks work fine because of the 2 errors which fix themselves
(ARM clock x 2 and per clock actually based on IPG which is AHB/2)
but flexcan can't work as it gets its clock from IPG and thus
calculates its bitrate using a reference value which is twice
what it really is.
