plat-sam: disable CFG_CORE_HAS_GENERIC_TIMER

sama5d2 platform does not have support for the ARM generic timer
extension. Disable CFG_CORE_HAS_GENERIC_TIMER and implement
plat_get_freq() using device-tree. Since clocks are probed early in
the boot process, the udelay function can be used at driver probe time
but not before clock probing of course.
