ARM: dts: stm32: add system-clock-direction-out on stm32mp15xx-dkx
The commit 5725bce709db
("ASoC: simple-card-utils: Unify clock direction by clk_direction")
corrupts the audio on STM32MP15 DK sound cards.
The parent clock is not correctly set, because set_sai_ck_rate() is not
executed in stm32_sai_set_sysclk() callback.
This occurs because set_sysclk() is called with the wrong direction,
SND_SOC_CLOCK_IN instead of SND_SOC_CLOCK_OUT.
Add system-clock-direction-out property in SAI2A endpoint node of
STM32MP15XX-DKX device tree, to specify the MCLK clock direction.
