From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
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.
