[PATCH V3 1/2] ARM: socfpga: Permit overriding the default timer frequency

[Marek Vasut]

The default timer rate may be different than 25 MHz, permit overriding
the default rate in board configuration file. Ultimatelly, this should
be properly handled by a clock driver, however that is not available
on Gen5 yet.
