Subject: [PATCH 20/38] arm64: dts: mediatek: mt6795-xperia-m5: Fix mmc0 latch-ck value

Change the latch-ck value from 0x14 to 4: as only bits [0-3] are
actually used, the final value that gets written to the register
field for DAT_LATCH_CK_SEL is just 0x4.

This also fixes dtbs_check warnings.

Fixes: 5a65dcccf483 ("arm64: dts: mediatek: mt6795-xperia-m5: Add eMMC, MicroSD slot, SDIO")
