arm64: dts: mediatek: mt8186: Fix systimer 13 MHz clock description
[ Upstream commit b391efba57ff085233d5ead5e01817bf4b71d999 ]
The systimer block derives its 13 MHz clock by dividing the main 26 MHz
oscillator clock by 2 internally. The 13 MHz clock is not a separate
oscillator.
Fix this by making the 13 MHz clock a divide-by-2 fixed factor clock,
taking its input from the main 26 MHz oscillator.
