clocksource: armada-370-xp: Get reference fixed-clock by name
The Armada XP timer has two mandatory clock inputs: nbclk and refclk,
as specified by the device-tree binding.
This commit fixes the clock selection. Instead of hard-coding the clock
rate for the 25 MHz reference fixed-clock, obtain the clock by its name.
