ARM: dts: renesas: r8a73a4: Fix external clocks and clock rate

Browse Source 
[ Upstream commit 090c409457 ]

External clocks should be defined as zero-Hz clocks in the SoC .dtsi,
and overridden in the board .dts when present.

Correct the clock rate of extal1 from 25 to 26 MHz, to match the crystal
oscillator present on the APE6-EVM board.
