Subject: ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz

commit c61f30a255550bbfc6b83c1ca720661489cac4c0 upstream.

On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.

This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.
